I seem to have permanently froze the enemies in front of me, and the rest of my board is all spores. Seems impossible to clear them out, and I also cannot die.
Might be good to add a turn timer to unfreeze, it'd be an easy way to prevent this from happening. I'd rather be killed for my blunder than be put in an infinite zugzwang like this.
you can always just burn spores. they have chances of dropping coins, and coins block spores, until you just burn all the spores to death. takes 2-3 hands of cards to do though.
