The objective of this addictive game is to move down 42 levels and avoid the crawling nasties. Some will kill you, others just make the game a bit more difficult. During the game things start moving faster, so pick up a clock every now and then to change time back to normal. The sparkles make you invincible for a few seconds. The blue crawlers are harmless. Best to avoid all other objects you encounter.
Move down by swiping down. Float over crawlers by swiping up. Jump high by tapping the screen anywhere to reach for example a clock.
Have fun!
