Do you like this new capsule

The logo now has a bloom effect and is more related to our game content, which includes tools, links, puzzles, and blueprint elements.

The background is cozier, cleaner, and features cats.

My game is a numerical puzzle game similar to Sudoku and Hashi. I am adding more elements and variations to make it more fun and cozy, not just numbers in the gameplay.

If you love my game, you can try our demo and wishlist it on Steam. I will keep you updated about this game. Thank you for loving my game!
