This is cool! It's a challenging game with how far in advance you have to plan your moves, and I enjoy it.
My recommendation is to make the UI more user-friendly. I couldn't figure out how to exit the tutorial or training room without closing the game, for example. And selecting the CPU character with the arrow keys sometimes didn't work, and I think it'd be better to select them with the same controls as the player.
I think with some refinement this'll be a fun and unique game
