This is a neat twist on a classic pen-and-paper game. I never thought I'd be able to destroy the walls of mazes as I explore them!
I like the simple visual design. It's oddly relaxing to watch the yin-yang character roll around. The enemies were more of an annoyance than a real challenge, but dodging them and purposefully pathing to avoid them added some interest to the game.
Another poster mentioned this, but since this game encourages dying so often the pause on the "Wasted" screen gets a little annoying. I think it would be fine to keep the text (or move it elsewhere on the screen, maybe small and by the spot where you died?), but not lock the player from moving.
