Hey, I fixed it, now it should work :)
Nice! I played through the loop twice. It seems pretty fun, but there's an inherent complication to getting new pieces since your opponent gets to use them too. Also I never saw slime blocks in the shop. In general, exploiting the enemy AI's inability to adapt seems to be the primary key to victory. Also the attack that adds stress to an enemy is super powerful-- if you 'collapse the tower' on an opponent they lose all their stats like normal but you can keep playing until you want to pass!
