I am Paul, the glass and I am sad because I am empty. To make me happy again, you have to fill me up. Your task is to draw a line so that the liquid refills me and I can finally smile again.
Try to find the best way to complete each level. Be creative and do not be afraid, you will find the right solution to make me happy again. Some levels seem very light, let's see if you can always get three stars. Good luck with it!
