Hi, I took the time to write a review. Firstly, the game is cool: it's more interesting than regular tic-tac-toe. Elegant UI and sounds, no unnecessary clicks. I'm happy that I don't have to fight with the UI and annoying animations, a rarity for indie games.
A better color palette would be nice: only the classic one looks aesthetically pleasing. Example: I used the Jade palette from the Piko framework; it's more aesthetic than Felt. But I can't change the hover, active, and color of UI elements. It would be great if the color theme supported more than just the playfield.
For fun you could do game watching like on Lichess. This is a good source of inspiration for future versions.
