I have to agree with the previous poster...
The snowball teacher is HAWT!
The game was awesome, it gets a bit boring after a while, but it's still fun. As said, it needs a story mode [perhaps a snowball tournament where you can play in bigger maps].
Also, the other players on your team can be a nuisance and can just get in the way...
I think that, instead of making snowballs straight away, you should have a key that makes you collect snowballs, and instead of the maximum being the number of enemies fight, have a maximum of, say, 5.
