This game is great! Outside of a small issue (when the spirit block is placed next to 2 groups it seems to choose a random one to clear), this game is incredibly fun and I am addicted to it!!

Thank you! It's not random, it actually has a priority, which is described in the readme file and on the store page - highest priority is the bottom, next highest is the side (toward the center), then the other side, then the block above. I wanted to try having it prioritize bigger groups first but I didn't have time!
