Here are just TWO games, I'll post now, there are more. But I think one is enough to kill you.
1st one is a mouse game.
You click and the bunny jumps. Keep jumping from each bell, and if you hit the ground, it's game over.

2nd one is fun, addictive, hard game. It's called World's Hardest Game. And trust me, they ain't kidding.
