Thanks for playing and for the feedback! The later levels have other pieces like the bishop/rook/queen that you can take and replace the sides of the dice with. Not sure if that mechanic was clear?
Yeah unfortunately I ran out of time to fix that bug, there's another bug as well where sometimes enemy pieces will hop over your pieces like they're knights. It was actually my first time making any kind of complex AI like this, and it was quite a challenge! So yeah the AI is a bit dumb, but at least it's functional ;)
Thanks for playing :D
