Cute monster designs. Colorful and detailed environment, which really looks like what it is supposed to be. (Is that Dracula on the wall of the classroom? "What is a man?...")
The music was pleasant, but too loud--the SFX were barely audible.
I think it would be cool if the children ran away and tried to hide behind the swings, the slide, the jungle gym, etc... that would add some fun challenge.
