Me too. It was in the second bullet-turret level, not sure if that's the final level. Dev, if you're intending to come back to this for some post-jam polishing, you could maybe put in a level select menu. Then people can jump straight back to where they left off if this bug hits them.
Great little game, really atmospheric and pretty. Just a minor bug is that if you collect the cards out of order they remain out of order in your card "deck". It might be nice if they auto-sorted themselves, so that the rightmost card is always the one most relevant to the current puzzle.
