The attack seems to be totally useless, the madness lacks an explanation for why the player takes damage out of nowhere, and enemies have a tendency to spawn on top of the player at the beginning of a new room. The best I could do was just running from room to room ignoring enemies. That run I got 11 rooms cleared, 1 coin, 4 emeralds, 4 rubies, and a total score of 350.
The visuals aren't bad, but I think the floor tiles would be better if they aligned with the directions of movement.
