I have also been encountering the locking up bug that appears to be showing up in the comments below. I'm able to play one normal game, but then I won't be able to play any more turns, and nothing appears to happen on the board.
Heya! Thanks for letting me know. I will take another look at the code and see what the heck is going on. The problem seems to be happening for everyone but me, so it's very hard to track down 😭
