You will have to tap on the screen in order to stay in the air. If you hit the floor you will die. If you hit the big white obstacles... well... you will die! You need to land on the green rectangles on the floor in order to desolve the obstacles and continue forward. This game requires high precision, fast reflexes and very, very, very stable nerve system. If you feel sudden desire to break your device it would be better to uninstall the app. You've been warned!
