Bringing back pieces is a nice twist. It allows the player to continue the game even when they have no more pieces on the board! They might even win. The mechanics are really interesting to explore. I like the similarities with normal chess pieces moves such as the bishop, rook, king. Although I can kind of see a stalemate happening wherein the two players are not using their life points and just avoiding each other. A king-like piece that the player can capture or maybe some punishment for not using up life points would be good for this since it will allow for some tactics. It has a really cool concept.

Interesting chess, maybe add more pieces? (It’s a jam, I know ^^) But the concept is nice!
