Run
Use the arrow keys or WASD to run through this crazy 3-dimensional course. If you want to turn up the intensity, hit pause (or press ESC or P) and change the game speed setting. If you want to beat all 50 levels of this classic game, you'll need enormous concentration and memorization! The levels only get harder as you progress, so focus becomes a more and more important attribute. This absolute classic was released all the way back in 2008!
