Mirror puzzles in Fireboy and Watergirl 2 Light Temple follow logical patterns once you know what to look for. These tips will help you solve them faster.
Trace the beam path backward from the target. Instead of randomly rotating mirrors, find the switch that needs light, then work backward to the light source. Each mirror along the path needs to redirect the beam toward the next mirror or the final target. This reverse-engineering approach in Fireboy and Watergirl 2 Light Temple solves most puzzles in seconds.
Rotate mirrors in 45-degree increments. The game snaps mirror angles, so there are only a few valid positions for each mirror. Try each position systematically rather than spinning randomly. Four clicks covers all possible angles.
Position characters before adjusting mirrors. Some mirrors are only accessible from specific platforms, and reaching those platforms may require the other character to hold a switch. Set up character positions first, then fine-tune the light path.
Prism levels require both beams to hit their targets simultaneously. In Fireboy and Watergirl 2 Light Temple, if one beam is correct but the other is not, adjust the mirrors closest to the prism rather than the ones near the targets. Small changes at the split point have larger effects downstream.
Do not overthink it. Most mirror puzzles in the game have a single correct solution with minimal mirror adjustments. If you find yourself rotating every mirror on the level, step back and look for the simpler path you might have missed.
