Here's a description of Run:
"Run is the most popular Flash Game, now available for Android from albinoblacksheep.com
You are an alien that can only run and jump. You run on the tiles of the floor, walls, and ceiling of outer space.
Keep in mind that when you switch walls, the game will stop time for you to get your bearings. It's not lag."
