Fireboy and Watergirl 4 Crystal Temple is a logical game about flame and water. It is the fourth part of the adventures of two opposites. Each one tries to get to the right door. But the path to it is dangerous and zigzagging. Without help they can not get to the end. They depend on each others help. There are places where only water can pass, and then places where only a flame can pass. You can play the game by yourself or you can invite your siblings, buddies, parents, and you can play together. Each character is controlled separately. Enjoy a lot of fun even in a logical game. Have fun.
