Boring.
The game was just boring and repetitive. All you do is kill kids in 1/6 ways then move on to the next wave. It would have been nice to have a bit more of a storyline, or at least stick to the one you started with ( where was the magic candy? Not to mention the HUD? ). Another thing that caused a great deal of grief while playing was the detection system for killing the kids; it was just too picky, and it made the gameplay very restrictive.
But on the positive side, you had a very nice "how to play" section, and the main character looked pretty cool.
Its a good start, but it has lots of room for improvement.
