Attack of the Snowmen

Little Timmy is being attacked by evil snowmen! Help him defend himself by building a fort and throwing snow at the snowmen!

Use wasd/arrow keys to move, press the spacebar to build/destroy, "z" to throw a snowball, and use "1" and "2" to switch between building and destroying. Be careful, because throwing snow and building uses up your "Snow". To get more, destroy Snow Piles or kill Evil Snowman!
