Cool game, the number of chess variations you were able to create are impressive! Some of the ideas are really clever. The presentation is clean and the start menu is laid out in a sensible way. Sfx and background music would help the overall vibe a lot. The theme application feels like a pretty big stretch and the fact that you also submitted the game to like 5 or 6 other jams makes it seem like you didn't really care enough to take this jam seriously tbh. That being said its a cool idea for a game and everything runs well. Nice work!
