Nice aesthetic and art, very fun gameplay idea. Would have been nice to see an explanation of the mechanic in the game itself, so it could be seen as standalone from the itch.io page. Also an AI would be nice to add some challenge.
I really wanted to add an AI opponent, but I quickly found out that chess AI programming was a rabbit hole I didn't have time to go down yet haha. Thanks for the feedback, an in-game tutorial definitely would've been a good idea!
