Ever look over the edge of a tall building and hear that voice in the back of your head tell you "... jump..."?
This game seems like it's entire concept was constructed from that very principle, often called "Lapelle Du Vide" or "Call of the void" though with a comical twist to the whole idea. The goal is simple, jump from a VERY high altitude (some go as far as space), come close enough to buildings and objects that you "kiss" or "hug" them without suffering the ill effects of free-fall collision, and try to land safely. BTW, instead of earning coins or something, the main currency you use to unlock new levels is "teeth"... I don't know why but it makes me just uneasy enough that I laugh every time I finish a level and it sais "You've earned X number of teeth!"
For those with vertigo or who have a fear of hights/falling, I don't reccomend this game as you'll probably find yourself reaching for a bucket every level. To everyone else, I absolutely reccomend this game.
