Step-by-step walkthrough
Lower white
Fireboy jumps up first from the left side of the starting shelf, then steers onto the middle stone platform. Jump right onto the white plate and wait for its lift to lower.
Take Small around the right side
Small can climb the little sloping middle steps and drop through the passage beneath white. Jump right off the lower slope onto the waiting blue ferry. Continue up the far-right staircase, jump left onto the ledge above it and walk left onto lowered white.
Raise Small to the narrow upper passage
Fireboy jumps left off white. Let Small ride the lift up, then walk left through the one-cell gap. Jump left onto the small middle platform and drop left onto the blue-lever shelf. Activate blue and let the long ferry arrive at its left stop.
Collect the middle blue diamond first
Watergirl jumps from the starting shelf to the middle platform, then left onto the blue-lever shelf. Stay to the right of the lever, jump up and right onto the small platform above for blue, then drop left and return to the starting shelf.
Collect the lower-left red diamond
Fireboy drops from the middle platform to the starting shelf and jumps left onto the short stone perch below the blue lever. Walk left along it for red.
Board the blue ferry
Fireboy steps off the perch to its right and lands on the waiting ferry. Watergirl walks left off the starting shelf onto the same ferry. Small uses the blue lever again to send them right.
Collect the bottom pair
Stay aboard while the ferry passes beneath the starting floor. Fireboy collects the bottom red diamond and Watergirl the bottom blue. At the right bank, climb the staircase, jump left onto the higher ledge and collect its blue diamond.
Lower white for the heroes
Small returns to the starting shelf, passes through the low gap and climbs the short middle slopes back onto white. Wait for the lift to reach the heroes’ ledge.
Collect red beside the white lift
Fireboy walks left across lowered white and drops onto the right end of the starting shelf for red. Move just clear of the tall pillar, jump up first, then steer right onto white. Watergirl boards too.
Raise both heroes
Small steps left off white. Once the lift reaches its upper stop, each hero crosses onto the long right shelf. Stand left of the next ledge, jump up first and steer right onto it. Fireboy collects its red diamond.
Cross the roof
From that ledge, jump up and left onto the high roof. Fireboy walks left for red; Watergirl follows the roof for blue.
Collect the left red and hold yellow
Fireboy continues left down the roof and drops onto the middle-left shelf. Drop left again onto the yellow ledge and jump for the red diamond overhead. Hold yellow until its ferry reaches the middle.
Collect the two left blue diamonds
Watergirl follows the roof left, collecting the high blue diamond as she drops onto the middle-left shelf. Step off that shelf to the left, then move right while descending to the lower shelf for the final blue diamond. All twelve are collected.
Bring Small onto yellow
Small climbs from the short middle step, drops left to the starting shelf and continues left onto the waiting yellow ferry. Fireboy jumps up and right to the middle-left shelf, releasing yellow and bringing Small across.
Enter the small passage
Small moves near the ferry’s left edge and hops onto the low left bank. Move close to the left wall, jump up first and then right onto the sloping shelf above. Walk right to the foot of the narrow zigzag.
Climb the zigzag
Alternate left and right between its short shelves. Before each higher shelf, stand beside its exposed end and jump up before steering inward; only Small fits the low corridors. From the top, jump left onto the pink ledge and hold pink.
Return the heroes to pink
Watergirl jumps left onto the yellow ledge, then up and right to Fireboy’s shelf. Each hero stands clear of the shelf above, jumps up first and steers left onto the pink ledge. Small keeps the bridge extended.
Reach the exit approach
Each hero jumps right from pink onto the inner stone shelf. Jump again over the sloping step onto the top of the narrow wall to its right.
Enter the matching doors
From that wall, jump up before steering left onto the extended pink bridge. Jump left onto the exit shelf and walk to the matching door. Red is nearer the bridge and blue is farther left; either hero may finish 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.
A gate or platform moved back
A pressure plate releases when its rider or weight leaves. Keep your partner on it until you are safely across. Levers stay set after you leave; check their ON or OFF state before crossing.
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.
