I like the vibes this game has, you have a solid mix of assets here. I really only have two gripes. 1. At first it's hard to tell the enemy is killing you, with no audio or visual aid it seems like the game is crashing. 2. I cannot seems to figure out what to do with the brass key. This may be due to either unclear design or me being dumb, the latter not being too unrealistic. Good luck with your future game making endeavors.
