You are in the monster land and are being chased by a big monster. As if it was not enough, you will have several obstacles on your way, like little monsters, boxes and spikes. Run for your life! The game central mechanic is the ability to grow and shrink. So you have to toggle between the little and big form to pass through the obstacles.
