Hot Boy and Watergirl
Game title: Hot Boy and Watergirl
Water and Fire! These are the basic elements we all know and they have opposite properties. Imagine two human-like characters that consist of fire and water. One of them is a boy and the other one is a girl. Together, they have a pretty serious set of skills and advantages, but it is impossible for them to walk through the levels of the game at the same time. When one of them walks freely, the other cannot make a step. You are to control both and make them pass each and every stage successfully.
