Step-by-step walkthrough
Load the hanging lift
Fireboy starts at the bottom left: jump left onto the hanging platform. Watergirl starts at the top right: push the square stone block LEFT onto the other hanging platform, then step back onto the dry right ledge. The heavier block lowers that side and raises Fireboy.
Send Fireboy up the middle
As his lift rises, Fireboy jumps right onto the left walkway. Cross the orange lava, then jump up the two central steps to the highest middle ledge. Keep him there while Watergirl opens the upper gate.
Reach the upper-right purple plate
Watergirl jumps left into the lift shaft and rides down, collecting the two blue shaft diamonds. Leave the shaft to the right, jump onto the small ledge by the right wall, then jump UP before steering left onto the purple plate above. Stay on the plate.
Open the exit gate
With Watergirl holding the plate, Fireboy jumps left from the highest middle ledge onto the upper walkway. Continue left through the raised gate and walk past the yellow lever. This opens the lower-left exit passage. Jump left once more for the high orange diamond above the shaft.
Bring Fireboy down through the diamonds
Return right across the orange pool and climb the central steps again. Drop onto the small ledge just right of the highest middle ledge. Jump left through the orange diamond to the middle shelf, then descend right to the lower island. Jump left to the lowest central island for the last orange diamond, then jump left into the red-door alcove.
Bring Watergirl down the right side
After Fireboy has finished using the upper gate, Watergirl can leave the purple plate. Drop around the right ends of the ledges, collecting the blue diamond near the wall and the one above the lower-right steps.
Cross above the goo and meet at the exits
Watergirl jumps left onto the low right island, then left again through the blue diamond above the middle gap. Use the small central island to jump left into the blue-door alcove. Stay above the long purple goo pool. Both heroes must be at their own doors to finish.
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
middle right
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Gate 1.
Switch 2
upper left
Walk past the handle, or use it nearby: Enter for Fireboy, E for Watergirl, or the touch Use button. Each use toggles it; it stays set after you leave.
Controls Gate 2.
Gate 1
upper left
At least one of these inputs must be active: Switch 1.
Opens the passage while its circuit is active. Wait until your partner is safely through before releasing a pressure plate.
Gate 2
lower left
At least one of these inputs must be active: Switch 2.
Opens the passage while its circuit is active. Wait until your partner is safely through before releasing a pressure plate.
Moving platform 1
lower left
The relative weight on its connected platforms drives this platform.
Loading one side of the pulley pair lowers that side and raises the other.
Moving platform 2
upper right
The relative weight on its connected platforms drives this platform.
Loading one side of the pulley pair lowers that side and raises the other.
Stone box 1
upper right
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.
A pulley is moving the wrong way
Loading one platform lowers that side and raises its partner. Shift the riders or movable weight as described in the route. A thin lift does not protect you from a dangerous pool when it sinks into the liquid.
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.
