The polish on this game is crazy! Enjoyed the mechanic, though it felt a bit clunky at times when I got confused as to which button would do which action (I did get used to it over time though).
The little imps were a cool touch, though I missed the one in the second level before I knew I could scale myself down! I don't really have anything else to say on this; the art was great, the music was fitting, and it was a clever mechanic suited to the theme. Good job!
Edit: Oh, also, I would have really liked some coyote time for the jumping! I fell off the edge of things trying to jump over way too many times.
