In this game you're a lonely person who enjoys the company of himself. He does it literally meaning that you can duplicate you character and make your duplicates help you. You can do it as many times as possible creating an entire army of you. Your goal in each level is to reach the green exit door. You'll need to jump over gaps and climb on higher platforms. Your own jumps are not always high enough to do that. What you need to do in these cases is to stand in an appropriate position and press space. This will make you return to the level start and will create a duplicate of you that will repeat all the movements you did before you've got to the point where you pressed space. It'll stop there and will stand there until you press space. You can use him to stand on his head and jump higher.
