If you need yet another way to kill time online, check out this free online video game.  Since the instructions only tell you how to move to the next level, here’s how to play:
UP ARROW = Pedaling.  Hold it down.
RIGHT/LEFT = lean forward or back. Use this to land the jumps.
Cheat tips:  don’t hold the UP arrow down constantly, you don’t need to go full speed the whole time, and it’ll save a lot of energy, helping you get to the next “energy pill” and make it further.  Balance yourself in mid-air when you jump by going back and forth on the LEFT and RIGHT arrows.
When you’re done, email the game developer and tell them that we, as cyclists, don’t approve of pill popping to win a race…we’re trying to clean up our image here.  Geeeez.
