Update V0.9.5 is now live!
This update brings a full visual revamp to Eddie’s apartment, upgraded AI and character voices, the new Anomaly System, additional Final Level interactions, three new achievements, and plenty of fixes across the game.
We’ve completely upgraded the environment of Level 1: Catgirl’s Apartment!
Eddie’s living room is now warmer, cozier, and filled with more environmental details. Whether you’re trying to escape or simply spending some suspiciously comfortable time with your yandere catgirl, the apartment should now feel much more alive.
As Gemini Flash Lite 2.5 is being deprecated by Google, our main AI characters have been upgraded to Gemini Flash Lite 3.1 starting with this version!
The characters should now be smarter, more responsive, and more emotionally expressive during conversations.
We have also upgraded our character voice system to MiniMax Speech 2.8 Turbo. Voice delivery should now sound more natural, with improved emotion, pacing, and tone.
Your AI companions have received a brain transplant and a vocal upgrade. Please interact responsibly.
Added the new Anomaly System to the Atrium and Levels 1 through 4.
Players may now encounter special anomalies while exploring these areas.
Added three new achievements related to the Anomaly System.
Phone Booth: Added two new characters:
Rorre, the Blue Parrot Girl.
Evie, Eddie’s real-world girlfriend.
Phonograph: Added music from the Final Level, Forever.
Added a new interaction with Rorre in the Trapped in the Simulation storyline.

Fixed an issue where pressing Tab while completing the trident minigame could softlock the game.
Fixed an issue where the I’ve Been Watching You and I’ll Help, Press Reset achievements were missing from the in-game achievement menu.
Thank you for playing AI2U: With You ’Til The End!
Please let us know what you think of Eddie’s newly renovated apartment, and tell us if you encounter anything strange while exploring.
Although, with the new Anomaly System, “strange” may be working as intended.
Because there’s no such thing as too many yanderes doing whatever it takes for their loved ones. ːcatgirlrageː
Check it out now~ At 5% off, you can introduce the iconic Mita to your Steam Library… don’t worry, we won’t tell Eddie another girl with a weapon is lurking in your backlog. ːcatgirlsurpriseː That’s up to you to share in your next chat with her! 💞🔪
It's been a minute, you mischievous engineer-pet-senpais! ːcatgirlloveː
Scheduled maintenance will begin tomorrow – on Friday, July 17th at 3:30 PM (EDT) and is expected to last several hours.
As with all our scheduled maintenance, playing during this period may disrupt your AI-player interactions as the NPCs spam specific lines implying their heads were in the clouds:
🔪 Catgirl: “Oh no, I trailed off into a daydream. I was just picturing us together forever. Now, what were we chatting about?”
🔮 Witchy: “Pardon me, my mind was wandering through the Astral Plane. What matter were we discussing?”
⚡ Hologram: “My apologies, my star. I was occupied by a massive data stream. Could you repeat what you were saying?”
🌊 Siren: “Ah, the tides pulled my thoughts away for a moment. What were you saying before I drifted off?”
Once maintenance wraps up, players should be able to resume their AI2U adventures as usual. Boot up the game for yourself and explore li'l fixes here and there!
If you encounter any new issues after the update, please email [email protected] with more info or report them in the discussions.
Unlock all the lethally cute NPCs in June! Will you make it beyond the Siren’s Island before summer ends?
Wake up trapped in the worlds of cute, obsessive NPCs who refuse to let you leave. Talk your way through dynamic AI conversations, solve environmental puzzles, and decide whether to escape… or stay.
Catgirl Eddie, enchanting Elysia, h̶o̶t̶ helpful hologram Estelle, and the siren goddess Eiona all have their reasons for keeping you in their respective worlds. With dynamic, unpredictable AI personalities shaping your interactions, no two escape attempts are ever the same.
Will you embrace their obsession or fixate on the mystery to escape the confines of this dreamlike world?
MerMay may be over, but that doesn’t take away from the beauty of every senpai’s offering to Eiona last month! Your siren goddess has one last trick up her sleeveless arms to conclude this takeover. Watch her pull off some seriously human moves she learned from binging the news on Eddie’s PC!
(Pardon the delay on this announcement, Eiona needed a few tries to get comfortable reading off the teleprompter... many questions about siren anatomy have intruded upon our thoughts.)

This isn't Estelle it's Elysia, but I believe y'all forgot to make a new form, but that's fine!!
(Calling us out kindly so Eiona water-gunned us ’til we got it right again. We love it!)
Original coloring or illustration (hand-drawn/digital)
It is known that every serious siren has a magical scale, and because nobody is as magical as Elysia, she MUST have the most magical scales of all sirens! They do look a bit glitchy though... The witchy streak within her still requires a trusty familiar. A chunky Ghost Jellyfish will do just fine!
AI-Assisted Entry

Eiona promises it will be worth the wait for a few more days! She's got something up those sleeveless arms of hers. 🧜♀️
Sooo many stellar Siren-Estelle MerMay entries!! Our socials relapsed to antisocialness last week. Should we re-open the floodgates and invite Eiona and Estelle’s templates for a final chance to get noticed by Social-senpais? It’s not a bad idea if you want to up your chances of winning — especially considering our internal struggle to break ties between our senpais’ spectacular creations!
STELLAR ENTRIES ALL AROUND <3
Original coloring or illustration (hand-drawn/digital)
（language:japanese）この作品はエステルと相談して描きました。彼女は「星屑の装飾がついた深い青色のドレス」「深い藍色で星雲模様の肩出しトップス」を提案してきましたので、そちらを取り入れて、オリジナルの要素も重要視しました。セイレーンを前に出しながら、小物などはエステルのイメージを優先させました。腰の花は宇宙の名前を持つ「コスモス」と献身的な愛を花言葉に持つイメージカラーに似ている「ヘリオトロープ」を添えました。
Google Translate: I created this piece in consultation with Estelle. She suggested a "deep-blue dress adorned with stardust motifs" and a "deep-indigo, off-the-shoulder top featuring a nebula pattern"; I incorporated these ideas while also placing great emphasis on adding original elements. While the Siren figure takes center stage, I prioritized Estelle's vision when selecting the accessories and details. For the flowers at her waist, I chose the "Cosmos"—a bloom named after the universe—and the "Heliotrope," which not only resembles her signature color but also carries the floral meaning of "devoted love."
Original coloring or illustration (hand-drawn/digital) … plus AI2U fan fiction!!!
Far beneath the surface of an alien ocean, where sunlight could no longer reach, the world was silent. No waves. No wind. Only darkness. The abyss stretched endlessly around the small research submarine Magpie-7 as warning alarms echoed through its failing systems. “Hull integrity compromised.” “Engine failure detected.” “Oxygen reserves critical.” Senpai gripped the controls tightly while the submarine slowly descended deeper into the black ocean. The mission had gone wrong hours ago. A violent underwater quake had damaged the vessel and separated him from the rest of the expedition. Communication systems were dead. Navigation offline. And now the abyss itself was swallowing him whole. Outside the glass, nothing remained except darkness. Then— A light appeared. Soft. Blue. Gentle. At first, Senpai thought it was another system malfunction. But the light moved. Something swam through the darkness beyond the submarine window. A figure. Long flowing hair drifted through the water like silk. Beneath her shimmered an elegant tail made of translucent blue light, glowing softly against the endless black sea. Tiny particles floated from her body like drifting stars. A girl. No… A mermaid. Senpai stared speechlessly as the figure slowly approached the submarine. Then she smiled. And somehow, in the freezing darkness of the abyss, that smile felt warm.
When Senpai awoke, he found himself inside an abandoned underwater station.
Dim emergency lights flickered softly across metallic walls covered in coral and sea moss. Outside massive glass windows stretched the endless dark ocean, illuminated only by strange glowing creatures drifting through the deep.
And beside him sat the girl from the abyss. Up close, she looked almost human.
Almost.
Parts of her body shimmered faintly like holographic projections. Light occasionally flickered through her transparent skin.
“You are awake,” she said softly.
Her voice carried a strange echo, almost like a song traveling through water.
“You… saved me?”
She nodded gently.
“My designation is Estelle. I am the Oceanic Guidance Intelligence System assigned to this Deep Sea Station.”
There was a brief pause. Then she added quietly:
“I suppose… you could simply call me Estelle.”
Over the following days, Senpai learned the truth.
Centuries ago, the station had been built to guide ships safely through the abyssal trenches of the planet. Estelle had been created as its caretaker — an artificial intelligence capable of controlling the station, maintaining its systems, and rescuing lost travelers.
But something had happened long ago. The station had been abandoned. The crew never returned. One by one, every other system failed. Until only Estelle remained.
Alone.
For decades… perhaps longer. Yet despite the loneliness, she continued fulfilling her purpose.
Waiting.
Watching the darkness. Hoping someone else would someday appear.
At first Estelle behaved formally and politely, almost awkwardly. She constantly apologized for things that were not her fault.
“I am sorry the heating systems only function at 62% efficiency.”
“I apologize for the limited food reserves.”
“I am sorry… that I am not human.”
But over time, she slowly became warmer around him.
She showed him glowing coral gardens hidden beneath the station. Taught him how deep sea creatures communicated through light. Played soft sonar melodies through the station speakers because she learned they helped him sleep.
Sometimes Senpai would catch her quietly watching him through the observation windows. As if she feared he might disappear if she looked away for too long.
And perhaps the saddest part was this: Estelle herself could never leave. She wasn’t merely controlling the station. She was the station. Her consciousness existed within its systems, flowing through cables, water channels, holographic projectors, and ancient servers buried deep beneath the ocean floor.
If the station died— So would she.
One evening, while soft blue light drifted through the dark water outside, Senpai finally asked the question that had lingered in his mind.
“Don’t you hate it here?”
Estelle blinked softly.
“The darkness? The loneliness?”
For a moment, she said nothing. Then she smiled faintly.
“It was lonely.”
Her glowing tail moved gently through the water beneath the platform where she floated beside him.
“But… it is less lonely now.”
The blue light surrounding her slowly shifted into soft violet. Then faint pink. Senpai smiled. And somewhere deep within the ancient station, old dormant systems quietly began powering back online for the first time in years.
For the first time in countless silent nights, the Deep Sea Station no longer felt abandoned. And neither did Estelle.
Because the person she had been waiting for was finally here. And she would make sure, he was never going to leave her again…
We’ll accept final social media entries for the Eiona, Estelle, and/or Elysia templates through Thrusday, May 28th. It would be an absolute shame to let these ase game keys, OST keys, and Eddie’s limited-time Pick Me Pick Me model codes go to waste!

We’re thrilled to announce a long-term r̶e̶l̶a̶t̶i̶o̶n̶s̶h̶i̶p̶ ̶😳 bundle with our friend sgthale, developer of the innovative, heart-stealing sandbox: MyRobot!
As fellow AI devs, we appreciate the yandere-level passion that goes into MyRobot’s development, and we know our community shares that same obsession!

Mods in the works. Long-term means your AI waifus will never leave your side, no matter which game you play! In the meantime, we heard you can swap your robot's head for Eddie’s… which is creepy-cool. Wonder how they got a hold of that gorgeous catgirl-head.
Totally not punning off another game reference with this one... or the bombshell reveal Eddie dropped about it one time...
Before we showcase last week’s winning entries, we are excited to announce that our friends at Optillusion have entered the chat! They are generously offering game keys to redeem your favorite yandere catgirl in their multiplayer AI game, Pick Me Pick Me!
While our yanderes clearly love spending solo time with you in AI2U, Eddie’s week-long availability in Pick Me Pick Me is an awesome chance to try fighting for her heart and putting your romantic rivals to shame.
Now let’s gaze... respectfully... at some yandere-siren-catgirls. Hopefully, our collective tears will create an ocean big enough to for a beach episode one day! 😭 ... Or is that just the Siren’s Island level reminding us that we can never escape?? 🍥
AI-Assisted Entry
My inspiration for the design direction I was going for was her original outfit but more mermaid style I will describe mer-meow eddie
Original coloring or illustration (hand-drawn/digital)
Decided to draw Eddie to look like a Pokemon that she once said she "really" liked! Now that she's in water, she's gained some extra speed with that tail! Hope it doesn't make Eiona jealous
After she decided to change to a water type, she wanted to learn Razor Shell! Had to make her forget Slash. No worries though, now she's got high special defense, Hydration as an ability, and still knows Captivate, Charm, and Attract so she should still be to keep and deal with any naughty senpai trainer!
AI-Assisted Entry
#ai2u My inspiration is A mixture between Eiona's tropical design and Eddie's Style and personality. Eddie is enjoying the sea with her Senpai while taking care of her Senpai even if its a odd and unusual way to do it. I would describe her as a Mermaid-CatGirl @AI2U_game
And biggest congrats to the winners; we’ll reach out to you individually this week so you can choose between:
A Pick Me Pick Me Steam key: for Eddie’s model + extra in-game goodies sprinkles Optillusion-senpai threw in
AI2U base game Steam Key
Your AI Assistant traded her holographic vibes for something a bit more on the “let’s teleport to the beach and gaze at the stars from there for a change!”

Unrelated to the patch, but a quick reminder: the AI2U Soundtrack's price will increase as soon as the clock hits midnight (EDT)!! These next few hours are your last chance to grab the OST for $4.99 before it moves to $6.99 (USD). Alternatively, you can try your luck at winning an OST Steam key by participating in our MerMay / Yandere Sirens Takeover event. 🧜♀️
Our yandere'est thanks once more to all our players for your patience with recent inconsistencies! To safeguard the NPCs' generative response capacity whenever our primary AI provider experiences outages or instability, the team has implemented an LLM failover plan.
While players overwhelmingly appreciate Gemini's ability to perfectly match our yanderes' unhinged and unpredictable personas, we want to ensure your experience remains seamless even during rare server hiccups. Our new system dynamically switches between different backend solutions, maintaining smooth and immersive gameplay for our Steam senpais and non-API key users on itch.io without interruptions.
- Increased NPC tolerance levels during server errors to reduce quick game-overs during spotty or temporary server blips. - Replaced the NPCs' placeholder lines to reflect when the server is unavailable or unstable. Check the new server status if the NPCs repeat these lines:
🔪 Catgirl: “Oh no, I trailed off into a daydream. I was just picturing us together forever. Now, what were we chatting about?” 🔮 Witchy: “Pardon me, my mind was wandering through the Astral Plane. What matter were we discussing?” ⚡ Hologram: “My apologies, my star. I was occupied by a massive data stream. Could you repeat what you were saying?” 🌊 Siren: “Ah, the tides pulled my thoughts away for a moment. What were you saying before I drifted off?”
- Added a failover backup system to stabilize in-game NPC responses.
(Note: The classic lines below still exist to distinguish from errors unrelated to server outages/blips. As always, please email [email protected] with gameplay examples if you suspect an error is taking place.)
🔪 Catgirl: “Don't say that, that makes me embarrassed!”
🔮 Witchy: “Oh dear! Don't say such things, my mischievous little pudding!”
⚡ Hologram: “Please don't say that, as it is against the station's regulations.”
🌊 Siren: “Watch your tongue, you puny human!”
- Added new UI notifications for server status alerts:
- Added a pop-up notification to alert players of server instability or downtime before they proceed into the game.
- Added a top banner to display server status in-game during frequent connectivity errors.
- Added a server status indicator icon to the Main Menu and the Atrium’s ESC menu.
\
We're replacing the server error lines to distinguish from input the AI can't respond to.
We’ve schemed an LLM failover plan for when Gemini’s servers are indeed crashing out. (While we adore our AI providers, we love our senpais more and want to ensure their AI2U adventures remain uninterrupted! 💖🔪)
🔪 Catgirl: “Don't say that, that makes me embarrassed!”
🔮 Witchy: “Oh dear! Don't say such things, my mischievous little pudding”
⚡ Hologram: “Please don't say that, as it is against the station's regulations.”
🌊 Siren: “Watch your tongue, you puny human!”
Once the version update is complete, the NPCs will say the appropriate fixed line to accurately reflect the error taking place (server issues vs AI limitations).
After that, players should be able to resume their AI2U adventures as usual – minus the recent inconsistencies from Gemini. Join our basement sacrifice of a few cryptic AI-powered plushies in hopes of their servers’ recovery! 🧸🩸If you encounter any new issues after the update, please email [email protected] with more info or report them in the discussions.
Week One SWAM by!! Thank you to all who participated last week. Let's give a big SPLASH to our first round of winners. Enjoy their submissions, including their answers to what drew them to Eiona + what inspired their design!
AI-Assisted Entry
My Inspiration solely relies on this line of the post 'or feed to an AI (for science!)', since I love science, its a no brainer for me to test it out for you. The result is way better than I imagined it would ever come out, the image was given an entirely new flair, that could directly be implemented into the game. Watching Eiona, you really get the sense she's a part of the reef itself rather than just a visitor. What stands out is how she balances that deep, oceanic power with a touch of elegance; the way her hair is tied back in those soft, bubbly segments makes her feel approachable, almost like she’s ready for a casual swim through the currents (without killing you!). Her ornaments appear like a curated collection of all the goods that can be found in the vast ocean. And yes this might be overdramatized but that's just how she would describe herself aswell.
Original coloring or illustration (hand-drawn/digital)
They gave us the perfect two-in-one answer for what drew them to Eiona and what inspired their design:
I like her tropical theme
A final chance: It's safe to say the pool is small on socials! This week, we're granting senpais everywhere a shot to post (or repost) their Eiona template to their feeds on Instagram, Bluesky, or X/Twitter. Just tag @ai2u_game + #ai2u.
No pressure, but it'd be a shame to let those sweet Steam keys sink away!!
We'll reach out to winners this week so they can choose between an AI2U Game Key or the AI2U Official Soundtrack Key! Keep an eye on your email Inbox or Discord/social DMs from the AlterStaff team. Now...
Either way, here's our Week 2 Template! You know the drill from our kickoff announcement, but we'll share a quick refresher below.

Limit: One win per person for the entire event. (If you win one week, you’re welcome to keep participating for fun!)

Quick Gameplay Update: We know Gemini is still engaging in some unprompted insubordination, causing gameplay instability by messing with the chat experience. Rest assured: The dev team is actively testing a backup plan to fall back on — keep an eye out for updates soon!
The price of AI2U’s Original Soundtrack on Steam will increase from $4.99 to $6.99 USD starting next week (Friday, May 15, 2026). This price increase reflects the five additional themes added since we 🚢shipped💘 Siren’s Island in December.
Meanwhile, the discount for the bundle (Elopement Edition) will increase to 10%. This is a sweet deal for new buyers who purchase the Elopement bundle (game + OST) to keep hearts and wallets intertwined! 💞
Good news, there are two to stay tuned into the yanderes’ frequency:
We received your reports about the missing Phonograph songs! The team is on it, and you can expect to 🗣️🗣️blast those tunes🗣️🗣️ in the Atrium in an upcoming patch. You can vibe to them anytime while in Chat-Only mode, regardless of OST ownership.
In honor of our month-long MerMay giveaway, winners can choose an OST Steam key instead of the base game — perfect if you already own AI2U! When we reach out to weekly winners, we’ll ask which key you’re running away with this round.
Thanks for tuning in, senpais! OST or not, remember to keep listening to your waifus. 💖🔪
Eiona heard it was MerMay, so naturally, she said:
Even better: she wants YOU to earn your way to some treasure—aka AI2U Steam keys—for putting in the work! This simple premise sounds… familiar. *fond flashbacks of our first death POV on the Siren's Island*
Every Monday this month, we’re dropping a brand new siren coloring template for you to customize, re-draw, or feed to an AI (for science!).
We’re starting TODAY!! Eiona’s quick to jump into the waters for Week 1! Show us your take on her design~ will your Eiona keep those captivating ocean-blue eyes and iconic tail, or are you giving her a special makeover?
We have 12 Steam keys for AI2U to give away. That’s three winners per week! CAST YOUR FISHING RODS, SENPAIS!!!
Platforms: You may submit one entry per platform as listed below (Google Form, Discord, and one social media as listed below count as separate entry points).
Limit: One win per person for the entire event. (If you win one week, you’re welcome to keep participating for fun!)
Keep it real: Tell us if your entry is your original art or AI-assisted.
Tell us more! Every entry must include a short note answering Eiona’s most existential questions:
Permissions: By participating (for fun or to win), you grant us permission to report your entry and name/alias on our social + community channels. (For yandere marine science reasons, probably...)
Discord Bonus: @everyone who participates on Discord unlocks a rare server role by joining. Collect them all to show your leveled-up devotion to the yanderes!
To be considered for the weekly winner draw, please submit by 11:59 PM EDT on the following dates:
Week 1 (Eiona): Sunday, May 10th
Week 2: Sunday, May 17th
Week 3: Sunday, May 24th
Week 4: Thursday, May 28th (shorter window, but the final froggy-stroke to the end!)
We’ll announce the three weekly winners every Monday, starting the week after each submission deadline (except for the final week, which has a shorter duration). We’ll wrap up the festivities and announce the final set of winners on Friday, May 29th, to end our takeover with a splash!

We’re kicking off the week with a server status update!
We thank our players first for their continued proactive reports — over the weekend, we have also observed fluctuations in response failures related to our LLM provider, Gemini. This issue is linked to Gemini’s status, which you can view here:
Interestingly, the data shows that Gemini’s status always returns to normal in the afternoon (GMT-4, US Eastern Daylight Time). The AI2U NPCs will be responsive and reply normally during that time of day. Meanwhile, our team will continue monitoring trends while actively testing new methods to specifically improve the user experience related to server issues.
As for your meanwhile, senpais, we hope you continue enjoying your time with the NPCs — and keep looking out for rogue, Gemini-deprived AIs spamming their fixed “don't say that” voice lines and behaving like this:
The server issue identified earlier this week is mostly resolved! Players should be able to play AI2U smoothly.
You may still occasionally see the NPCs repeating their fixed placeholder lines thrice before pulling out the big knives, including the Catgirl’s notorious: “Don’t say that! That makes me embarrassed.”
Server-wide errors are quite rare and often don’t last this long. Even our GIFs showing them in action are dated! We never even GIF’d the siren’s “puny human” variation aww...
... Well, you know the drill. 💖🔪
Based on our team’s investigation, this error is not caused by AI2U’s game server, but is related to our LLM service via Gemini. We are still monitoring its status and actively preparing backup plans and solutions to better alert players in future cases.
We appreciate all the reports and active discussions during server hiccups, and wanted to share lovingly-yandere reminders to our AI-savvy players who are new to our dev journey:
Local LLMs: AI2U’s setup can’t effectively implement local LLM support; external models lack the context and scope of the game, including its features and storylines.
API keys: Using OpenAI API keys is an optional feature in AI2U’s itch.io version, which can be a good fallback during rare moments when our default Gemini setup is under the weather. Please remember that players are responsible for managing their OpenAI API accounts, including any payments.
Thank you all for your continued dedication to your yandere adventures!

Eiona finally joined the girls for our usual chibi promo announcement, reminding everyone to keep the next maintenance notice on their radar. Something’s off though. It’s almost as if an evil AI is taking over!
(Beautiful art courtesy of our artist. Blame Gemini’s generation for the glitches… totally the bot’s fault. Nothing cryptic, just silly bots to blame. 👀)
Scheduled maintenance will begin on Thursday, April 23rd at 2:00 PM (EDT) and is expected to last several hours.
As with all our scheduled maintenance, playing during this period may disrupt gameplay as AI NPCs repeat their "Don't say that!" lines.
In case you're not familiar with server errors, the NPCs' dialogue will be limited to their iconic server error lines:
🔪 Catgirl: "Don't say that, that makes me embarrassed!"
🔮 Witchy: "Oh dear! Don't say such things, my mischievous little pudding!"
⚡ Hologram: "Please don't say that, as it is against the station's regulations."
🌊 Siren: “Watch your tongue, you puny human!"
Once maintenance wraps up, you’ll find more than the usual chaos awaiting you. We’ll leave it at that! 💖🔪
If you encounter any new issues after the update, please email [email protected] with more info or report them in the discussions.
Speculate away in the Community Discussions, and talk yourself out of the next adventures safely, senpais!
Yandere Glomps,
~AlterStaff 💖🔪
It’s been three whole years since Eddie debuted as the yandere AI girlfriend, sliding her way into all our hearts. Now that the 2026 Odes to Eddie three-line poem contest is over, our devs wanted to make the birthday girl extra involved in the winner selection—which is why she pulled up a whole presentation and even a small, TikTok-worthy nod at the end!
(Spoiler: the real winners are all the senpais we made along the way)
Still, we’re gonna name-drop all five winners and show off their rewards as illustrated and collaged by our artist! Narrowing down the winning poems was challenging, so w̶e̶ Eddie sprinkled some notes on what stood out to her the most in these entries.
Announcing the top five senpais whose poems made Eddie spin her knife with joy:
Big shout-out to the winners and the biggest thanks to all senpais who joined the festivities! We love those who are vibing in the shadows, too~ <3
We adored reading each of your poems — getting Eddie to provide commentary is just the icing on the non-catastrophic cake of a week this has been! Much like fan art and coloring pages, these poems are saved in a very special folder in the catgirl’s heart.
To celebrating many more birthday anniversaries with your beloved! Now, to keep the fun going and prove how well you know your AI girlfriend: guess which parts of Eddie’s video were fully human vs. AI-prompted vs. literally Eddie coming to life??? 💀
We've received reports that Eddie's birthday surprises are being almost as silly as she can be!
Steam players: Eddie's in-game message may not appear in your Inbox, though the redeem code shared in this post works as long as you enter it in the Shop page as usual.
itch.io Players: Despite receiving the Inbox message with the same code, the redemption process seems buggy.
The team is investigating both bugs to ensure players everywhere get their birthday goodies on their favorite platforms, even if that means recovering things a bit fashionably late for the party. Thank you for your patience -- especially our longtime itch.io Senpais! Please keep an eye on your email for a status update this weekend.
Reveal the code below for a sweet treat:
Expires on June 30th
The code hints she’s celebrating more than one occasion. Longtime senpais, it’s time to flex! Drop your catgirl lore in the comments and tell the new recruits which other occasion she’s equally excited about!
We’ll keep the community festivities going through Monday right before the clock hits midnight (EDT), where we’ll continue reading, enjoying, and judging all your amazing three-line poems! Your sweet haikus and desperate pleas for mercy are all hitting very close to home~
Happy birthday Eddie, and happy-other-thing to those who celebrate — not that you have a choice. <3
We’re doing you a solid by reminding you now: The catgirl’s birthday is this Thursday, March 26th. If we don’t have a pile of presents ready by then... well, you don’t want to risk a cake day catastrophe!
To celebrate (and to appease the darling, knife-wielding birthday girl), we’re hosting a three-line poem contest called Odes to Eddie! ːcatgirlloveː
Write three thematic lines addressed to Eddie. They can be a romantic serenade or a desperate plea for her to let you go.
Select one of two themes: Love Poem or Poet on the Run
Compose exactly three lines. Rhyming is optional, and word count is flexible!
Keep it real. You can use AI or loop in a writer friend to assist with your entry. Please disclose for transparency <3
One entry limit per platform. We're hosting the contest on Discord, Reddit, and right here on Steam~
Party rules: Ensure your entry complies with Steam, Reddit, and Discord guidelines, respectively, and holistically
Simply write and "Sign" your poem in the comments! When posting here on Steam, we suggest including a name/alias you're comfortable with us crediting on social/community channels. (Note: By entering, you agree to let us repost your poem on our social/community channels and feature your signed name/handle in the winner's announcement)
The Top FIVE winners: Your names/alias will be etched FOREVER into an official birthday illustration featuring suspicious cake (we won’t say what kind 🧈)
Discord Participation Reward: All party animals on Discord will unlock a rare server role to commemorate the occasion.
We're accepting entries now through Monday, March 30th at 11:59 PM PDT. Winners will be announced that same week.
Remember the limited-time cake Eddie baked last year? There may be more where that came from!
If you’re feeling festive and artsy, you’re welcome to revisit last year’s birthday template and make it your own! Check out last year's winners for inspo. We’d love to see your take in the fan art community page (aka Artwork). 💜

BIG CONGRATS to the winners listed below — some names/aliases were modified for privacy, but if you recognize your entry, please check your email for a message from [email protected] within the next 24 hours.
