It's an iphone app that's a horror-survival game that I completed years ago, but I was REALLY OBSESSED WITH IT.
It's a game about a boy name David who wakes up with a bomb implanted inside of him and he has to solve these puzzles that were set up by the two antagonists name White and Black. The story deepens a bit more as you meet more people that David doesn't remember, and it gets really interesting later on. (I'm not going to spoil the game D:)
It's apparently 5 dollars (i think because I actually lost my itouch) but if there are anyone interested in playing it, then go ahead and play it! :D I would highly recommend it for you escape gameers though :)
