Step-by-step walkthrough
Free the small friend from the left stairs
Fireboy drops from the right end of his starting floor and walks to the blue lever below. Turn it on so the small friend can descend the first two steps. Turn it off for the next leftward crossing, then on again for the last low gate. Wait for each gate to finish moving before crossing.
Power the first fan
The small friend descends onto the floor with the blue lever, walks right beneath the low wall and holds the timed green plate.
Collect the upper diamonds
Fireboy and Watergirl take turns entering the central fan and steering right onto the upper roof. Fireboy collects red in the shaft and on the far-right slope. Watergirl collects blue in the shaft and on the roof. Continue down the right slope to the white plate.
Cross the timed white bridge
Watergirl holds white while Fireboy jumps left from the right-hand ledge onto the extended bridge. Walk towards its left end, then jump left again onto the small shelf for red.
Bring Fireboy to the right fan
Drop around the right side of the red-diamond shelf onto the middle ledge. Walk off its right end onto the lower floor and continue right towards the second fan.
Move the small friend through the timed fan
The small friend leaves green and immediately moves left into the fan. Steer right onto the roof as soon as the friend rises high enough; the fan stops after the plate’s short delay. Follow the roof and right-hand slope to hold white.
Bring Watergirl to pink
Watergirl crosses the white bridge, descends around the middle ledge and holds the pink plate on the right. Fireboy rises in its fan and collects the high red diamond.
Use the small friend’s low passage
The small friend leaves white, jumps left onto the moving bridge before it returns, then jumps down-left to the middle ledge. Follow the right-hand lower floor into the active fan. Steer right over the narrow wall and descend to the floor below.
Open the yellow gate
The small friend walks left through the low tunnel beneath the upper floor and holds yellow. Watergirl steps off pink so Fireboy can descend safely before crossing left.
Collect the central blue diamond
Each hero crosses the open yellow gate, leaves the upper floor at its left edge and lands beside the central tower. Jump upward before steering left onto its top shelf. Watergirl collects blue.
Open the bottom orange hatch
Watergirl drops around the tower’s left edge, walks right through the bottom water pool for blue, then jumps out at its right lip. Hold orange to move the hatch above. The small friend can now walk right through the low tunnel and drop through the opening.
Power the final fan
The small friend crosses the bottom water pool, jumps out at the left lip and holds the pale blue plate. Watergirl returns across the same pool and Fireboy descends from the central shelf.
Collect the final left-hand diamonds
Each hero enters the left fan from the bottom floor. Fireboy collects the low red diamond and Watergirl collects blue above it. Steer right onto the exit ledge while the small friend keeps the fan powered.
Enter the matching doors
Fireboy enters red and Watergirl enters blue. 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.
