Watergirl: WASD to move (W to jump). Fireboy: Arrow keys to move (Up arrow to jump). Both characters need to reach their colored exits to complete each level.
Watergirl can collect blue diamonds and walk through water; Fireboy can collect red diamonds and walk through fire. Neither can touch green slime - that kills both.
Coordinate to step on switches, push blocks, and redirect light beams (in this Light Temple version) to clear obstacles.
Plan Both Routes Before Moving - Looking at the level once with both characters in mind beats running one of them blindly into a hazard.
Use Pause to Strategize - When the puzzle is complex, pausing lets you map out what each character needs to do without time pressure. Light Beams Need Aiming - The mirrors in Light Temple rotate; experiment with angles before committing to a configuration.
Don't Forget Diamonds - You can finish a level without collecting all gems, but completionists chase the full set; some require careful coordination.
Switch Order Matters - When both characters need to step on switches in sequence, the order often determines whether the puzzle solves; if one approach fails, try the reverse.
