Jesus christ, this game has been making me tear my hair out for the past couple of days.
The setup? You're a ninja. You have superior agility, and the ability to wall jump on your side. Your objective is to finish a set of maps in a set amount of seconds, usually two minutes (you can obtain more time by collecting yellow dots, two seconds per pop). In order to proceed from one level to the next, you have to touch a bule button and go into a door that it opens. The only problem is that there are robots, mines and stationary turrents impeding your progress, plus you die if you fall from too high of a precpice.
With a shitton of levels, and three levelsets to start out from, you're in for frustration, but damn it's fun when you fake out heat seeking missles and make it to the exit in the nick of time...
