According to the developers, all you need to know to play this game is 1) Use the arrow keys, and 2) Think fast. The levels will test how fast you can make your Bubble-Bot do four things - climb, run, survive, and defend. In each mission, you have to stay alive for as long as possible. Once you fail, you will move onto the next mission. After you have failed at all four, your score will be combined to see how well you did. If you have lightning quick reflexes, this game will be easy for you. If you don't, you may struggle.
