Step-by-step walkthrough
Lower the upper-left bar first
Both levers begin OFF. Fireboy follows the upper path RIGHT through orange lava, then jumps into the yellow-lever alcove near the right wall. Walk past the lever to switch it ON. Jump back LEFT from beside the lever and return over the central crest. The yellow bar on the upper LEFT now lowers into a stepping position.
Collect the two high orange diamonds
Fireboy jumps LEFT from the central crest, using the lowered yellow bar to reach the high-left orange diamond. Return RIGHT across the crest to the yellow lever. Walk past it again to switch it OFF and raise the bar, opening Watergirl’s return path. Step clear to the RIGHT of the handle, then jump for the high-right diamond. Wait here while Watergirl takes her upper route.
Open the right passage with Watergirl
Watergirl follows the blue pool to the LEFT and drops into the small lever chamber below it. Collect the blue diamond and walk past the purple lever. Before leaving, make sure that lever is ON: it keeps the sliding bar away from the right-hand descent. Use the little sloping ledge on the left to jump back up to the blue pool, then return toward the center.
Bring Watergirl down the right shaft
Watergirl heads RIGHT from the central start, jumping over each orange pool separately. Collect the blue diamond near the shaft and drop through the passage opened by the purple lever. Land in the blue basin below and collect its diamond.
Bring Fireboy down the left side
Fireboy returns LEFT along the upper route, then drops around the far-left outside wall. Follow the lower ledge right, making separate jumps across its three blue pools. Collect the orange diamond between them. Use the tiny dry ledge in the middle to enter the alcove with the next orange diamond.
Descend onto the central islands
Both heroes continue down to the small islands above the wide purple goo pool. Land on one dry island at a time. Fireboy collects the orange diamond above the low-left island; Watergirl visits the low-right island for the final blue diamond.
Cross to the matching exits
Fireboy crosses from the center to the low-right island, then to the small island beside the RIGHT wall, and finally the orange-door shelf. Watergirl returns through the central island, the low-left island and the small left island to the blue door on the LEFT. Wait on each dry landing before jumping again. Both matching exits finish the room; all twelve diamonds earn a perfect clear.
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.
