Step-by-step walkthrough
Reach the upper-left lever
Watergirl jumps right from her starting ledge onto the middle shelf. Jump onto the left crate for the high blue diamond, then jump back left onto the upper roof and walk past its lever. This turns the mirror towards the warm beam.
Hold the upper-right green plate
Fireboy jumps left onto the middle shelf and its right crate. Jump from the crate for the high red diamond. Jump right onto the upper roof and stand on green so Watergirl can enter the far-right corner.
Take Watergirl across the upper pool
Watergirl returns to the middle shelf and crosses the upper pool. Push the right crate onto the right bank, then jump onto it and up to the roof. Collect the blue diamond beyond the green shutter while Fireboy keeps green pressed.
Refreeze the upper crossing
Watergirl returns left across the pool. Jump upwards before steering left onto the upper roof, then walk past the lever again. Wait for the cold beam to freeze the pool. Fireboy can now cross left safely and jump onto the upper-left roof for its red diamond.
Weight the two middle plates
Fireboy drops around the left roof and through his middle lava pool, collecting its red diamond. Push the left crate onto the purple plate at the far left. Watergirl returns right, collects the diamond in her middle water pool, and pushes the right crate onto the orange plate. Leave both crates holding their plates.
Enter the two inner chambers
The weighted plates move the middle passages aside. Fireboy walks through the left opening, then left along the inner shelf for its red diamond. Watergirl uses the right opening and walks right along its shelf for the blue diamond. Drop to the lower shelves underneath.
Exchange lower chambers
Fireboy drops into the bottom centre, lands on the third crate and jumps right onto the lower-right shelf for its red diamond. Watergirl uses the same centre crate to jump left for the remaining blue diamond. All ten diamonds are now collected.
Prepare the two bottom gates
Fireboy drops to the bottom floor on the right of the centre crate and pushes it left onto the yellow plate. Watergirl drops to the bottom floor and stands on the blue plate to the right. The crate opens the right passage; Watergirl opens the left one.
Get Fireboy beyond the left gate
Fireboy jumps onto and over the weighted crate without pushing it off yellow. Continue left through the lowered blue gate and stop on the small raised stone before the fan shaft. Watergirl can now leave blue. Keep the crate on yellow for her right-hand passage.
Ride the outer fans and steer towards the exits
Fireboy enters the left fan and Watergirl enters the right one. As each fan lifts the hero above the outer wall, steer outwards: left for Fireboy and right for Watergirl. Clear the wall and drop into the matching exit alcove. 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

This switch has no connected device in the current room.
Switch 2
upper right
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 1.
Switch 3
middle left
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 2.
Switch 4
middle right
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 3.
Switch 5
lower center
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 4.
Switch 6
lower center
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 5.
Moving platform 1

The air current pushes up. Stay in the stream until you can move onto a dry landing.
Stone box 1
upper 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.
Stone box 2
upper 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.
Stone box 3

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
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.
