Players must control both Fire boy and water girl using the arrow keys. The left and right keys control one character, whilst the A and D keys control the other. Due to the dual controls, this is also an amazing two-player game. Each of the 30+ levels has a different set of challenges. Players must think hard about the order in which they move Fireboy and Wategirl as they explore the light temple levels. Fireboy, for example, cannot walk over the blue water pools.
