This is a mini game of trying to score as much points as possible by getting damage to your body when falling down the stairs. It's not grapfically explicit, but morbidly fun. NSFW tag cos coworkers might start taking the elevator in fear of running into you in the stairs after they see what you are playing on your lunch break..
Sounds easy? My bf's High Score is 101860 atm. An average fall should get you about 30k and you are doing it right.
Install the game and start tripping.
