Not bad. Visuals are cute and the sound design is appropriate. I think I ended up getting about 5 levels in before I gave up because of the sluggish controls. When you have the run button held down, your character doesn't always go fast, mainly 1) when they are changing directions in midair or 2) jumping and THEN pressing a movement key. Makes it very frustrating to cross large gaps. I probably would have been willing to continue past where I gave up if there wasn't a lives system that forced me to start at the very beginning.
