«Инопланетяне не играют в судоку — они играют в COSMIC HOLES!»

The demo of my alien puzzle game is now available for Windows and Linux !

Have fun!

Just a heads-up: it's a bit strange... You'll have to stick with it to discover the unique mechanics of this logic game based on the Taoist theory of the Five Elements!

For RPG Maker MV users: It took a lot of trial and error to figure out the right way to export a version that runs natively on Linux WITH Greenworks ( https://github.com/greenheartgames/greenworks/releases ). I finally used the following setup: NWjs v0.33.3, Greenworks v14, and the Steamworks SDK v142. An important point to make this setup work with my game: do not use the 32-bit versions of the NWjs files for Linux, and do not rename the 64-bit versions of the NWjs files for Linux to ...64!

Originally available for Windows, porting it to Linux was a bit of a puzzle for me, but I actually enjoy that...

You can try out the demo version of this game of logical reasoning on Steam while you wait for the full version, scheduled for release on November 10, 2026.

Get ready to enter a strange, alien universe where the conventions of video games are challenged, and where you’ll discover the complex and natural (!) laws governing this universe before solving 300 logic puzzles (handcrafted using constraint solvers).

Hi.

I'm looking for playtesters for my puzzle game on Windows: "COSMIC HOLES Junior" on Steam.

The game is fully developed and features 300 handcrafted puzzles with constraint solvers. The demo, now available on Steam, includes 20 puzzles so you can experience the game's intriguing early stages and discover its unique features.

I’m currently fine-tuning the in-game hints, which is why I need the help of playtesters.

If you're interested, I can send you my PRESS KIT and a key for the beta version. My contact page: https://cosmic-holes-puzzlegame.top/contact/

Thanks in advance!

Hello everyone. I invite you to try a game that immerses you in an alien universe with its own strange yet highly engaging mechanics. Imagine logic, geometry, and a complex system inspired by the theory of the five elements.
The game demo gives you a taste of this emerging complexity: TRY THE DEMO

The full game (LINK) will take you on a journey of increasing difficulty across a total of 300 puzzles. It’s suitable for both adults and children.

Feel free to discuss the mathematical aspects of this game here.

COSMIC HOLES Junior is a logic puzzle game that offers a smooth learning curve and unique gameplay mechanics that challenge you to think on multiple levels at once.

“Relaxed” because my previous game, COSMIC HOLES, featured puzzles that were quite difficult to solve, and the game would assess your skill level to make things harder as soon as you started to get comfortable (with action as you figure things out, along with visual and mechanical twists to throw you off). In COSMIC HOLES Junior, I’m offering a much more relaxed progression, and the game will let you play at your own pace.

In COSMIC HOLES Junior, you must fill holes with colorful balls that spin at different speeds. These speeds depend on their electrical charge, which is influenced by the other colorful balls. The game requires strategic thinking on two levels: classic logic, similar to Sudoku, and timing-based logic related to the energy of each colorful ball placed.

You'll have access to a total of 300 logic puzzles. Each puzzle offers stars to collect, granting you access to the depths of a cosmic maze. A permanent in-game guide (in the upper-right corner of the screen) shows you how the colored balls interact with each other. If you get stuck on a puzzle, the game will partially fill in the grid for you, but you’ll need to replay that puzzle later to collect all the stars it offers. Finally, the puzzles are divided into 4 groups based on their size: at first, you’ll only have access to the small ones, then you can choose which ones you’d like to solve depending on your mood that day.

Give it a try with the demo available on Steam:

I’m using RPG Maker MV to create a game featuring 300 logic puzzles: grids that you need to fill with colored elements that spin at different speeds depending on their energy level!

You can try it out now on Steam:

I’ve been working on my game “COSMIC HOLES Junior” for a while now.

In a nutshell: first, imagine an alien Sudoku where the numbers are colored elements; then imagine that you have to choose not only where to place each element, but also in what order! That’s because the elements charge and discharge each other, and you must avoid overloading them at all costs!

You can try it out starting Tuesday, May 12, 2026, on Steam: https://store.steampowered.com/app/4693750/COSMIC_HOLES_Junior_Demo/
