The game has two modes; World Challenge, Levels.
The World Challenge is basically a rummy25.comsurvive mode – the moment you touch the screen the monster will start rushing at the finger and your goal is to survive as long as possible, afterwards, you save your score and it is shown in the Top Scores screen – challenge your friends too!
In the level mode, after you've survived 15 seconds in one level, you can unlock the next level - until the final level which after you completed it you get a very special achievement!
