A classic of our time! Help Watergirl and Fireboy to reach the exit door and pass to next level. The game includes different types of levels (with different types of difficulties); some of them require you to advance in group, others to go as fast as you can, others to move blindly. At the end, the goal is always the same: make both of them to reach their respective doors.
Use the A-w-D keys to move Watergirl, and the arrow keys to move Fireboy.
