I think the concept of this was really neat. And the overall feel was fun! My feedback would be to have the UI help say "don't mate white kings" cause that confused me. It's mentioned in the tutorial but at the bottom, I skipped thinking it was just chess rules which is partly my fault. But the game has in big letters "mate all red kings". Also, a minor/insignificant bug I discovered was if I spammed clicked really quickly they could all stack on the same tile. Great game idea! :D
