Equilibrium
In Equilibrium, you're just minding your own business, riding a unicycle on a tightrope. Use your mouse to balance yourself so you don't fall over. There will be a meter underneath you to give you clues as to whether you're too far over or not. If you drag the rope down and release it, it will bounce you up in the air. Someone decided to start throwing balls in your direction, and while the blue ones give you points, the red ones will kill you! Some balls are down low but many are up high so you'll have to use your jumping skills to stay in the game in Equilibrium.
