Thank You. I've sent a request to Valve, but we'll have to wait 1-5 days. As soon as I get the keys, I'll let you know.

I added a new update (new difficulty levels relax/training etc.)

I added a new update:

• Added new difficulty levels, available from the Options menu or before starting the game (later an option will appear to disable the pre-game window).

• New upgrades, e.g., faster XP gain.

• Slightly adjusted level balance.

• Added separate leaderboards for each difficulty level.

• Updated localization (around 200 translations).

• Other minor bug fixes.

• Updated the browser version (Chrome, Firefox, MS-Edge).

@PatchSO1967 Thank You. You start with one bullet, collect XP, and pick mutations (Split, Ricochet, Explosive etc.). After 2–3 upgrades it clicks together (mix). Glad it runs well on phone.

PS. An update will be coming soon that will add a difficulty level.

Hello,

I just released THE KULKA, a one-button bullet-heaven arcade where your single shot mutates and evolves into chaos.
Flap to dodge, collect XP, and mix crazy upgrades in real time.

Mutate. Evolve. Survive.
Each level adds a new mutation — Split, Ricochet, Homing, Explosive — stack them all and watch the screen melt.

Inspired by Flappy Bird, Vampire Survivors, and Pattern Survivors: Bullet Hell.
Fast neon visuals, instant restarts, endless chaos.

Created by Airem — one-person indie studio.

Just leave a comment

Hello,

What makes it unique?
In this roguelike bullet hell, you don’t just dodge patterns — you design them. Build your own attack formations using an in-game editor, create your tower-based defenses, and unleash waves of chaos across the battlefield.

Save Anytime System:
Save and quit at any point — even mid-battle — and resume later exactly where you left off. Every bullet, every wave, and every upgrade is preserved.

Key Features:

• Attack Pattern Editor — design your own bullet formations.

• Real-time chaos with hundreds of projectiles on screen.

• Save Anytime system (even during fights).

• Local leaderboards

• Cross-platform support: Windows, macOS, Linux.

💬 Feedback, thoughts, or performance notes are welcome — I’m a solo developer and every suggestion helps improve the game further.
Thanks for checking it out — chaos awaits!

Not a problem! I’m happy to hear the game helped you feel more confident with strategy and puzzles. That means a lot. Thank You.

Thank You @!SookieScreams¡

I did some quick tests, but didn’t play for long. I think it's playable 100%, but is it comfortable?

If you enjoy mobile gaming and notice anything that could be improved — feel free to let me know!
I’m happy to make changes to make it better for phone players.

Nobody likes them.... But if there are any bugs let me know.

If you miss any options in the game, or you have an idea to change something in the game, let me know.

Update 1.1.2

🌀 Pattern Survivors Update (Demo + Full Version)

Platforms: Windows (32-bit & 64-bit), Linux (64-bit), macOS (64-bit) and web version

This update brings a set of technical improvements, bug fixes, and deep engine optimizations for PatternBULLET2D Engine by Airem.
Performance and stability have been improved across all devices — especially noticeable on low-end hardware.

🔧 Changes & Improvements

• Online / Offline Leaderboard System
– When the player finishes a run with an active internet connection, online rankings are now displayed automatically.
– The system detects the connection and switches to online mode when available.
– If no connection is found, it switches to local ranking, which can later be manually updated by switching from online to local.
– Local scores are not overwritten unless the player chooses to update them.

• Improved Streaks.js System
– Fixed rare logic issues with combo and multiplier tracking.
– Smoother score progression and better streak handling during long sessions.

• Major Engine Performance Boost (PatternBULLET2D)
– Optimized logic and rendering loops.
– Improved memory management and particle caching.
– Average framerate boost on low-end systems: +25–50%.
– Faster loading times and smoother transitions between levels and effects.



• Bug Fixes & Stability
– Fixed minor logic bugs in collision and visual systems.
– Improved fullscreen/window switching behavior.
– More reliable save-state system across campaign and survival modes.

Update 1.1.1

💻 Cross-Platform Update

This update covers all versions of the game: Windows (32 & 64-bit), Mac (64-bit) and Linux (64-bit). Each platform received engine tweaks, better memory handling, and lower CPU/GPU load during heavy on-screen chaos.

I’ve also fixed an issue with the Steam Overlay that prevented it from launching on certain setups. It should now work correctly across all platforms (if not, please report it in the support thread).

⚙️ Improved PatternBULLET2D Engine

My custom bullet engine has been optimized for massive waves and hundreds of active units. Expect smoother motion, more precise collisions, and better effect management — while keeping that distinctive Pattern Survivors style.

In short: more bullets, fewer FPS drops.

🛡️ Unit & Projectile Fixes

1. The “Shielder” unit was reworked for performance; its shields and animations should no longer cause frame dips after wave 5.
2. HOMING projectiles now have smoother motion and smarter target tracking.
3. General AI and performance improvements for other units.

🌐 Online Leaderboards (Steam)

From now on, the demo also supports online leaderboards, letting players compete on the same terms as the full version.

To keep things fair, leaderboards are separated — demo and full edition each have their own score tables.

Every death, every wave, every save — it all counts now.

🌍 Localization & Assets

This patch updates 30 languages (more coming soon), covering both in-game text and Steam store pages.

Dozens of translations were refined for clarity and formatting; graphics, logos, and library art were also refreshed.

🧹 Other Fixes & Optimizations

1. Removed leftover internal test code (“code cleanup pass”).
2. Minor sound and effect polish.
3. Font alignment fixes in several languages.
4. More stable save behavior in Sandbox and Survival modes.

It’s not a huge content update, but a solid foundation for what’s coming next.

PS. You often ask me about $$$. You can record video of all my games with sound and music and display ads in streams/youtube/vimeo etc., collect donations etc., You can also share video gameplay if you want, the link on the forum or upload it to Steam -> https://steamcommunity.com/app/3787880/videos/

Presskit: Not ready yet.

Thank You :D

Thank You!

Ok, that's good. If there are any issues in the future, let me know, because on itch.io I can create a special website like Cataire Demoware and the Chromebook will run fullversion like a normal website.

Thank You 

My games have Geforce NOW options but I don't know if all of them are available. NVIDIA is slowly growing its catalog.

Honkai Star Rail seems to be available now: https://blogs.nvidia.com/blog/geforce-now-thursday-honkai-star-rail/

PS. Write to me at info@airem.pl if nvidia NOW does not run CATAIRE (I have another idea).

Or maybe GeForce NOW: https://www.nvidia.com/en-us/geforce/forums/gfn-announcements/22/393472/geforce-now-comes-to-chromebooks/

Maybe You can install Steam:
