Great game, I played it to the end because it was very fun. Great mechanics and really nice, simple artwork, which fit the game well. One suggestion: the light mechanic was not totally clear to me as I was playing. By the end I think I figured out that the beams are the light, but I still don't know why only one of them was rendered in white (vertical beam in second light level), while all others in the game seemed to be rendered in black, which made it unclear to me that those were "light." Perhaps they were meant to be in white? Hope that's helpful -- great game!
