The world is upside down, at least from this little guy's perception.  He has the power to walk on walls and turn it as upside down.  No, his powers are not like that of spider walls as this guy literary turns the world upside down to get where he want to go. The idea of the game is to get in the door, which you need to find.  There will be some coins to collect. You are not required to collect the coins, but they will surely increase your points.  Sometimes, you would need a key to open the door, but the rules will be quite the same.
