Step-by-step walkthrough
Open the lower green passage
Fireboy jumps onto the low middle shelf, crosses his lava pool and jumps left onto the green lever shelf. Walk left to the green lever. Watergirl walks right through the newly opened bottom passage and collects the lowest blue diamond.
Bring Watergirl up the middle
Watergirl jumps left onto the safe right end of the lava shelf, then left again onto the green lever shelf. Walk left across green, jump right onto the next shelf, and jump nearly straight up before moving right onto the higher middle terrace. Collect the blue diamonds on both shelves and walk right across cyan.
Light the beam
Fireboy jumps left from green onto the yellow lever shelf, collecting its red diamond and turning on the lamp. Leave yellow, return across green to reopen the low passage, then step off the green shelf’s left end and fall to the bottom.
Turn the lower mirror
Fireboy walks right along the bottom, jumps onto and over the short dividing wall for its red diamond, then walks right to the purple lever. Watergirl steps right off cyan and returns left across it so cyan is off.
Collect Watergirl’s right diamonds
Watergirl returns to the high middle terrace, jumps right onto the diagonal upper wall, follows its slope, and jumps right onto the right stone ledge. Step left off that ledge for the blue diamond beside the middle wall, then descend right onto the low right shelf for its blue diamond.
Use the diagonal crystal
From the low right shelf, Watergirl stops slightly right of its left end, leaving room overhead beneath the diagonal stone. Jump nearly straight up before steering left onto the middle diagonal wall, then move up its slope. Jump right onto the higher diagonal stone, continue right over the short wall, then walk right into the diagonal white crystal. She emerges at the left wall.
Reach the orange lever
Watergirl walks right along the left crystal shelf and jumps onto the shelf above for its blue diamond. Jump left onto the highest left shelf and walk left across orange. Wait there with orange on.
Bring Fireboy around the lower route
Fireboy jumps left over the bottom dividing wall, returns left to the safe end of the lava shelf and repeats the climb past green to the high middle terrace. Cross cyan to turn it on, then return left along that terrace.
Collect Fireboy’s right diamonds
Fireboy jumps right onto the upper diagonal wall and across to the right stone ledge. Walk down its right slope for the red diamond. Return left up that slope and jump onto the tall left end of the ledge, then step off its left edge and descend right for the lower red diamond. Continue right into the diagonal white crystal.
Cross the raised upper-left gate
Fireboy emerges on the left crystal shelf and collects its red diamond. Jump onto the shelf above, walk right through the gate held open by orange’s beam setting, and reach the raised right tip.
Open the roof route
Watergirl steps right off orange and returns left across it to turn orange off. Wait for the beam to lower the upper-right yellow gate. Fireboy jumps right from the raised tip onto the exit slope, moves left to the top of that slope, then jumps up before steering right onto the roof.
Collect the roof red and reset white
Fireboy walks right across the roof, through the white lever, to the last red diamond. Return left through white to switch it off, stopping just left of the lever. Wait for the white gate to lower completely.
Clear the rising white gate
Fireboy nudges right just far enough to switch white on, immediately returns left to the gate and jumps left over its rising top. Continue left onto the roof’s small left end. This short hop must happen before the gate rises into the roof passage.
Bring Watergirl through the upper route
Watergirl steps right off orange and returns left across it to switch orange on again. Wait for the upper-left gate to rise. Jump right onto the upper-left shelf, walk through the gate to its raised right tip, then jump right to the exit slope, collecting the final blue diamond in the air. Walk right onto the exit floor, stopping before the doors.
Finish at both matching doors
Fireboy steps left off the roof and drops onto the exit slope. Both heroes walk right onto the exit floor. The white and yellow gates now leave this lower passage clear. Watergirl stops at the blue door and Fireboy continues to the red door; either can arrive first.
This route was verified in the game simulation using player controls, required diamonds, and both matching exits. It describes this version’s independently reconstructed room, not an official walkthrough.

If you get stuck
Check the unfinished objective
The diamonds in this room are optional. If you only want to finish, bring both heroes fully inside their own matching doors.
You missed a moving platform
Return to safe ground and use the connected switch to bring it back. Board before your partner releases the plate or changes the lever. Avoid jumping into its underside; line up with the open shaft first.
You cannot recover safely
Pause and choose Restart level to reset both heroes, diamonds, weights, and switches. Previously completed levels stay saved. Follow the step order before moving a box or releasing a weight.
