This is a really cool idea! It reminds me of one of the mini-games from Kirby 64!! No notes really, except that I'd love to see what this would like singleplayer with an enemy AI!
Haha you are right, I don't remember that from K64 so many years ago, but I looked it up - this is very reminiscent of checkerboard chase. I would definitely be interested in pursuing some AI for single player. I'm not sure how to do that elegantly, but have some ideas. Thanks for playing!
