Very nice tile work on the backgrounds, cool understated background music. It took me a while to figure out how the controls work exactly, but it's a neat idea. Sadly, I couldn't find my way out of the first five or so rooms, maybe would have been nice to have some kind of hint what kind of goal I'm supposed to be working toward. (First I was like, maybe I need to defeat all the enemies? But then they seemed to respawn when changing rooms?)
