Move using arrow keys. You can go diagonal is you press two buttons at the same time. --If you are ever stuck on a level, press 1 to go to the first level, press 2 to go to the second level, press 3 to go to the third level, and press 4 to go the the fourth level--
All of the levels are possible, I have done them all. If you do touch a bubble, you only have to restart the level that you are on. THERE ARE 4 LEVELS *Rage warning*
