Step-by-step walkthrough
Open the right passage
Fireboy jumps onto the right tip of the left-hand shelf and holds yellow. Watergirl crosses the small rise in the middle passage, then climbs beside the raised yellow gate to the right-hand shelf.
Reach the green button
Watergirl jumps left onto the upper sloping roof, collecting the high blue diamond on the way. From the roof’s higher end, she jumps onto the top-left platform and holds green.
Bring the crate downstairs
Fireboy pushes the crate left off its shelf. Drop beside it, jump over to its left side and push it towards the lower end of the long central ramp. Move the Small friend out of its path first.
Help the Small friend climb
The Small friend jumps onto the crate, then onto the right-hand tip of the central ramp. Walk left through the narrow corridor and wait near the green gate.
Load the pink lift
Fireboy jumps around the crate to its right side and pushes it back towards the left-hand lift. Leave it over the lift, then jump to its left side. The Small friend passes through the open green gate and holds pink to raise Fireboy and the crate.
Leave the crate on yellow
Push the crate right onto the yellow button. Stop pushing early and let it settle; it needs to stay on the shelf. Fireboy steps off the lift’s left edge and returns along the middle passage.
Collect the top-left red diamond
Fireboy climbs the right-hand shelf and sloping roof to the top-left platform. Hop over the raised green gate to reach his diamond. While Watergirl still holds green, bring the Small friend back through it and down the central ramp to wait near the yellow passage.
Collect the middle blue diamond
Watergirl leaves green, follows the upper roof right and drops towards the middle passage. Jump onto the lower end of the central ramp and walk partway up it for the blue diamond. Return down the ramp, jump over the small rise and pass beneath yellow.
Explore the lower-right shelves
Watergirl drops to the shelf with the upper orange button, steps off its left edge onto dry ground below and collects the bottom-right blue diamond. Fireboy follows through yellow for the red diamond underneath the right shelf.
Collect the lower red diamond
Fireboy jumps left from the upper orange shelf onto the right ferry. Jump back to the shelf to collect the red diamond above the ferry, then hold its orange button. The Small friend follows the right-hand shelves to the bottom floor.
Collect the lower blue diamond
Watergirl jumps from the dry bank onto the right ferry. The Small friend holds the bottom orange button to move that ferry left. Watergirl jumps above it for her blue diamond, then jumps back to the dry bank.
Send the Small friend across
Release the bottom orange button and let the right ferry return. The Small friend jumps onto it; Watergirl then holds that button to move it left. With Fireboy still holding the upper orange button, walk the friend across the joined ferries beneath the low stone column.
Reach the silver diamond
Fireboy steps off the upper orange button so the left ferry carries the Small friend left. Wait for it to finish moving. Jump from its left edge onto the dry left bank to collect silver. For the return jump, take a short run-up on the bank before jumping back to the ferry.
Bring the friend back
Fireboy holds the upper orange button again. Once the ferries meet, walk the Small friend underneath the column to the right ferry. Watergirl releases the bottom button so it carries the friend right. Jump back onto the dry bank.
Return everyone to the middle passage
The Small friend climbs the narrow zigzag steps at the far right. Watergirl jumps from the lower bank onto the upper orange shelf; both heroes climb its right-hand step and jump left through the yellow passage. Keep the crate on yellow until all three are safely back.
Use the crate as a step again
Fireboy returns to the crate’s shelf and pushes it left off the edge. Jump around to its left side and bring it back below the long central ramp. The Small friend uses it to climb the ramp, then jumps onto the upper roof through the small opening at its left end.
Operate the final gate
The Small friend follows the roof right and jumps onto the blue button’s shelf. Stay clear of the button while each hero climbs the right-hand roof to its higher left side. Hold blue only when that hero is ready to jump into the exit chamber, because the lowered gate also blocks the route beneath it.
Finish at both doors
Let the first hero enter, release blue while the second climbs into position, then hold it again for the final jump. Walk into the matching doors with all nine diamonds collected. Either hero can 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.
How this room’s mechanisms work
Switch 1

Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 1.
Switch 2
upper center
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 3.
Switch 3

Switch 6

Moving platform 1
lower center
At least one of these inputs must be active: Switch 1.
When powered, it moves left; when power is released, it returns.
Moving platform 2
middle left
At least one of these inputs must be active: Switch 3.
When powered, it moves up; when power is released, it returns.
Moving platform 3

At least one of these inputs must be active: Switch 2.
When powered, it moves up; when power is released, it returns.
Moving platform 4
upper right
At least one of these inputs must be active: Switch 6.
When powered, it moves down; when power is released, it returns.
Moving platform 5
lower left
At least one of these inputs must be active: Switch 5.
When powered, it moves right; when power is released, it returns.
Moving platform 6
middle right
At least one of these inputs must be active: Switch 4.
When powered, it moves up; when power is released, it returns.
Stone box 1
middle center
Walk against its side to push it along its supporting surface.
A box can provide a step, load a counterweighted lift, or hold a pressure plate where the room’s layout allows. Follow the room route before moving it.
If you get stuck
Check the unfinished objective
Count the ring-marked diamonds still visible. All 9 are required before both matching doors can finish this room; each hero collects their own color.
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.
