Players take control of two characters, Fireboy and Watergirl, as they explore and overcome obstacles in a mysterious forest temple in the first installment of the well-known puzzle game series, Fireboy and Watergirl in the Forest Temple. In order to solve a number of physics-based puzzles and gather gems along the way, Fireboy and Watergirl must collaborate closely.
This Fire and Water game has several progressively harder levels, each with its own set of obstacles and traps, including green slime, ponds of water, lakes of fire, and bridges that move on their own. To control both characters simultaneously, players need to have both intelligence and coordination. For instance, opening pathways and resolving puzzles with switches, buttons, and other mechanisms.
