We loved the art style and the game loop :) It was fun to try and figure out if we should continue flipping the cards or just move on. We expected the 2nd and the 3rd loop to be harder, but the 1st lvl of the 2nd and 3rd loop seemed unchanged. Music got repetitive after a while but that's understandable. Strong submission nonetheless!
ps.
We managed to get to the 3rd loop when everything broke down. Monsters stopped attacking, you could open doors for free etc.
