Very nice & cute art all around ! A nice little concept and I enjoyed playing it.
Perhaps it's me, but I had trouble to figure out the level visual cues at first (roofs), what to avoid, etc. I reset many times in places I didn't necessarily expect to be reset, and backtracking, in my experience, was very unforgiving. In fact, I can't for the life of me figure out how to get to that third heater :P
