Chess with a twist, I like it. This is actually one of the more unique games I've played in this jam, as I did not expect to come across a chess game. I really like the mechanic you've added. It's simple, but it's also fun chaining moves together. The audio and graphics are also done really nicely, I like the visual and audio cue the game gives when you activate a combo.
I'm not sure what I'd add to improve the game considering it's chess. Maybe add a bot to play against, but that's obviously way too much work for a one-week game jam.
Nice game and great idea, I'm glad I came across it.
