DO NOT FEED THE VIRUS news & patch notes

Main Mode

• Stage 3 basic parasite movement speed has been reduced back to its intended value.

• Fixed a bug where a Swarm sound would be triggered when starting a run or upon entering the Upgrades menu.

Don't forget to restart your Steam client to update the game.

First Major Content Update

Three weeks after launch, we're releasing the first major content update.

Our focus since release has been simple: expand the game with new ways to play while continuing to improve the overall experience based on your feedback.

Today, we're introducing a brand-new Roguelike Mode, a rework of Stage 4's Gate mechanic, 12 new achievements, gameplay improvements, and more.

New Game Mode: Roguelike

Defend your virus against endless parasite waves, build powerful combinations through random upgrades, and survive long enough to defeat the final boss of each difficulty.

As you progress, you'll unlock additional upgrades that can appear in future runs, allowing for increasingly powerful and diverse builds.

Features

• 3 difficulty levels:

  • Normal

  • Hard

  • Nightmare

• Dedicated leaderboard for each difficulty

• New unlockable upgrades

• Save your run at any time

• Fully separate progression from the main campaign

The new mode adds several additional hours of gameplay and offers a completely different experience from the campaign.

12 New Achievements

We've added 12 new achievements, all focused on the Roguelike Mode.

Whether you're aiming for 100% completion or simply looking for new challenges, there are plenty of new goals to pursue.

Stage 4 Rework

One of the most common pieces of feedback we received concerned Stage 4 and its Gate mechanic.

We've completely redesigned how Gates are created.

Before

Two specific Veins had to be destroyed to create a Gate.

Now

Destroying a Vein automatically creates a Gate connected to the previously destroyed Vein.

The mechanic is now much smoother and easier to use while keeping the strategic decision-making intact.

Stage 4 has also been rebalanced around this new system.

Gameplay Improvements

Automatic Biomass Collection

Remaining biomass is now automatically collected at the end of each round.

Smarter Soldiers

Soldiers now deploy more effectively around the Core and make better targeting decisions.

More Dynamic Workers

Workers now wander around when no biomass is available.

Improved Parasite Behavior

Parasites now briefly pause before attacking the Core or Minicores after reaching them.

Additional Changes

Audio

• Reduced Overfed upgrade volume

• Reduced Swarm Wave volume

• Increased Cursor Miss volume

Fixes & Polish

• Fixed Continue button highlighting in the Upgrade screen

• Fixed an issue where the Continue button could sometimes fail to appear in the main menu

• Updated several upgrade icons

• Renamed Overflowing Veins to Overflowing Veins II

Thank you to everyone who has played, shared feedback, reported issues, and suggested improvements since launch.

We're excited to continue expanding the game, and this is only the beginning.

See you on the Roguelike leaderboards.

Hey everyone,

It’s been 2 days since launch, and the support for DO NOT FEED THE VIRUS has honestly been amazing. Thank you to everyone playing, streaming, sharing clips, reporting bugs, and leaving reviews.

We’ve also seen the feedback about the game length and amount of content. Well, we hear you, and we’re already working on it.

We’re now preparing a big update focused on replayability.

The first bonus game mode: ASCENSION.

This mode will add randomized upgrade choices, and more content overall. Instead of the skill tree, you will have to choose your upgrades wisely to finish this mode. It will emphasize the tower defense aspect of the game, but I will not spoil the rest.

Oh, and there will be multiple difficulties.

Here’s a small prototype preview:

We want to support the game actively so that you can replay it past the main campaign.

If you’re enjoying the game, leaving a positive review helps us a lot and really supports future updates.

Thanks again for the huge support these past 2 days.

After months of development, balancing, polishing, and bug fixing… here it is!!

What the game contains:

• 5 unique stages (demo was the first one)

• 165+ upgrades

• Allied units to develop your colony

• New mechanics every stage

• 23 Steam achievements

Our goal with DO NOT FEED THE VIRUS was to create a short incremental game that respects your time. We wanted progression to feel fast, satisfying, and constantly rewarding, without unnecessary grinding or filler. A lot of care also went into making upgrades feel meaningful and keeping the experience as polished and smooth as possible from beginning to end.

We also released a Supporter Pack if you want to support the game further. It includes exclusive cursor skins and a special in-game badge as a small thank you for helping us.

Nothing that will help you feed the virus tho.

Buying the Supporter Pack will also directly help fund an extremely important part of development: cat (& dog) food for our studio supervisors.

If you enjoy the game, leaving a Steam review really helps us more than you might think. As a small indie team, reaching our first 50 reviews would make a huge difference for visibility and help more people discover the game.

Thank you to everyone who wishlisted, played the demo, or simply followed the project along the way ❤️

We’re getting very close now!

It’s been incredible seeing so many YouTubers play the game already, including RCE, Blitz, Idle Cub, GrayStillPlays, and ImCade. Watching people experience the game for the first time has honestly felt surreal for our tiny 2-person studio.

Here are a few videos below (demo & full game)👇

Good news, we also wanted to mention that the game is currently playable on Steam Deck. Sadly, we don’t personally own a Steam Deck yet, so we haven’t been able to fully test and verify everything ourselves; if you try it there, we’d really love to hear how it runs and what could be improved.

We’ll also be launching with 23 Steam achievements for players who want to fully complete the game,

Thanks again to everyone who wishlisted the game, played the demo, shared feedback, or simply followed development along the way. It genuinely helped us get here.

If you haven’t wishlisted yet, now’s the time: Launch is on May 14.

Release time will be 5 PM GMT+2.

🇫🇷 France / 🇩🇪 Germany — 17:00 🇬🇧 UK — 16:00 🇺🇸 New York — 11:00 AM 🇺🇸 Los Angeles — 8:00 AM 🇯🇵 Tokyo — 00:00 (May 15) 🇦🇺 Sydney — 01:00 AM (May 15)

Welcome to DO NOT FEED THE VIRUS! Demo arriving next week

Hey everyone, We are really happy to finally open the Steam page for DO NOT FEED THE VIRUS. This project started as a small one-week experiment during a game jam, but we saw enough potential in the mechanics to keep pushing it toward a full release.

What is the game about?

The game is a mouse-only active incremental where you absorb biomass to feed a core. It is designed to be a condensed, satisfying experience. The final game will be about 3 hours long. We wanted to give you the choice in how you progress:

• Active Play: Max out your cursor power to do the heavy lifting yourself.

• Colony Automation: Focus on recruiting little creatures to automate the process for you.

The Demo is coming

A 30-minute demo is already finished. It is currently being tested on Itch to make sure we catch any stability issues before bringing it over here. We want the Steam experience to be as stable as possible for everyone, so we expect to have it live here in about a week.

Wishlist and Support

If you like what you see, feel free to wishlist the game. It really helps us out as we head toward the final release. We look forward to hearing your thoughts on the gameplay and the pacing very soon!
