I like the art of the game and the idea that you came up with. (Beating up little kids.. pretty evil!)
I wasn't sure how to avoid the teacher, I kept getting caught but I think I won at the end!
Something that I thought was a little strange was when you click one of the things to interact with like the swings or drawing with the chalk. I felt like I was stuck in the animation when sometimes I wanted to walk away and go punch a kid.
Good job on it though its original!
