Happy Wheels 
Have you ever wanted to crash your character into the wall and kill him when playing those 2D racers, like in Trials HD? It's always satisfactory to do so when things go bad, but you cannot find a better game than this to do so in. The game has three levels made by the creator, and a bunch of awesome levels made by players. 
You got three racers to choose from so far, all of which have special abilities.  
So far the game sounds pretty normal, right? Well, check this replay out. 
Yeah, thought so. You have to play this now.
