In Punch Micheal the rules are pretty simple all you have to do is beat Micheal up. You can go to the store to buy multiple "power ups" that will help with your "quest" to beat Micheal up. One ability helps make your punches a lot stronger. Also the lore behind the alien creature is that the species of Leahcim has almost gone exstinct and you find one while beating Michael up, so you decide to beat it up aswell. Once you reach 1000 points or more press the space key to change the backdrop and then you can do it again when you reach 10,000 points.
