Really fun and a clever idea. I really liked the core idea and being an actual piece on the board made for fun movement patterns. Having a match of your piece kill you brings a higher level and nuanced kind of excitement and tension to matches. There were a couple moments where I died after a big chain which are somewhat randomised and a little hard to math out before a match (the timer also limited the ability to pre-calculate). I think smaller levels could help that and would also force the player to solve the situation a little more rather than travel to an easy match. Really great stuff!
