Thank you so much for the kind words, Maya!
Yeah, there were a few bugs that I was having trouble reproducing in testing (doubling up, or bones just magically changing other pieces into bones!). And you're right... there wasn't any guarantee a level was finishable. I tried to counteract this by making the clear requirements significantly lower, but it only lessens the sting when you get a failed board. I think it's missing one more 'tool' for the player to use to feel better, but a simple reshuffle feels wrong. Certainly something to noodle over if I decide to add more post-jam.
Thanks again for playing <3
