Step-by-step walkthrough
Move both heroes to the upper side shelves
Fireboy jumps left for his lower red diamond, falls through the green crystal and jumps for the left middle red diamond. Return to the left starting shelf and enter the outer purple crystal. Follow the safe red pool and rising bank, jump for the high red diamond beside the central shelf, then wait. Watergirl now takes the mirrored route: lower blue diamond, green pair, right middle diamond, outer white crystal and high blue diamond. Both heroes must complete these starting crossings before either lever changes a platform.
Fireboy visits the left lever shelf
Fireboy descends along the left-side steps and red pools to the pale-blue lever shelf. Walk into the lever handle so it turns on through physical contact. This lowers the platform near Watergirl’s exit. Leave the lever on, descend to the left starting shelf, then use the purple crystal to return to the upper-left bank.
Finish Fireboy’s diamond route
Jump onto the central upper shelf and cross right for the next red diamond. Return beneath that shelf for the remaining red diamond. Descend through the left green crystal and steer right from its partner to the right starting shelf. Wait there while Watergirl completes her route.
Watergirl visits the right lever shelf
Watergirl descends along the right-side steps and safe blue pools to the orange lever shelf. Walk into its handle and leave it on, lowering the platform near Fireboy’s exit. Descend to the right starting shelf and use the white crystal to return to the upper-right bank.
Finish Watergirl’s diamond route
Cross the central upper shelf for the upper-left blue diamond, then return beneath it for the last blue diamond on the right. Use the right green crystal to return to the left starting shelf. All ten diamonds should now be collected, both levers should be on, and both platforms should be fully lowered.
Drop to the lower exits
Fireboy walks inward from the right starting shelf onto the lowered orange platform; Watergirl walks inward from the left shelf onto the lowered pale-blue platform. Wait to land before turning outward. Walk under the starting shelves and drop to the matching doors: Fireboy goes right, Watergirl left. Either hero can enter 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.
