It seems like everything Mordecai and Rigby do gets them in trouble. No matter where they are, or what they do, they always end up with someone chasing them. Today they upset the Moon Monster, and now if they do not play the right song on the keyboard, they will pay with their life. In the Power Keys game, you need to help Mordecai and Rigby follow the sequence that appears on the keyboard.
Get ready for an adventure in space, and no matter what happens, do not give up after the first tries. The rules of the game are straightforward. All you need to do is follow the keyboard, and see which keys you need to press. Even you complete a session of keys in the right way, you will electrocute the Mood Monster. When you miss a key, and you do not complete the keys session, you will lose a life. You have only three lives, and you can see them on the upper left side of your keyboard. On the right side, you have the score you managed to achieve, and on the left side of the keyboard, you can see your power.
Be very careful because each time you lose a life, the Moon Monster gets closer to you. When he catches you, the game is over, and you have to start it again. Keep in mind the order of the keys, and try as much as you can to remember all of them in the right order. Mordecai and Rigby are counting on you to help them this time. Do not let them down, and show them you are a good friend.
