If you've ever had a..friend...tell you that it's easy to be good at first person shooters because all you need to do is "click on their heads", then this game is for you. The objective of the game is fairly straight forward - trolls will spawn in increasing numbers and rush towards you. Your job is to click on their heads. If you do that, you progress. If you don't, you lose the game when they touch you.

So practice a little with this game, and eventually your...friend...will regret that they ever brought up the phrase.
