I had fun, nice game with a great aesthetic. I made it to the third floor, gathered more than 60 coins, and died before ever finding the elevator. I would have retried if I had respawned on the same floor instead of at the beginning of the game.
Also. be careful not to place two related door entrances that require moving in the same direction, like with the elevator. It makes you release the up key at exactly the right moment to get out of the room, which can be annoying.
