Up to Snow Good is a Uncle Grandpa game from Cartoon Network website.
Help Uncle Grandpa save his friends from Evil Snowmen that he accidentally summoned.
This game is a tower-defense like game where you have to hit the incoming enemies before they reach you. You also cannot hit your friends, for if you do the game will end. The game revolves around using the arrow keys to move up and down amongst the rows and the spacebar to throw snowballs.
Hit the snowmen in order and make sure you mind your spacebar hits. If you mash the spacebar button you'll end up accidentally throwing a snowball at your friend.
For the badge achievements that call for charged snowball throws, start doing the snowball charges (by holding the spacebar for a few seconds before you throw) in the very beginning of the game. If you wait til future waves the snowmen will be coming on too fast for you to charge up.
