Step-by-step walkthrough
Take Fireboy to the upper centre
Fireboy walks up the small slope beside the bottom pool and jumps left onto the long sloping shelf. Climb the left stairs and cross his lava pool. From the right side of the small high shelf, rise before steering left onto it, then jump right onto the central roof. Wait on its right side.
Open the diamond chamber
Watergirl jumps right from her starting pool onto the central sloping path. Jump up its short vertical step, then jump left onto the blue lever shelf. Touch the lever once and leave it active; its blue panel opens the bottom of the right-hand diamond chamber.
Take Watergirl to the upper-right timer
Return down the central slope to the bottom. Jump right from the dry slope beside the large pool onto the sloping exit roof. Jump left to the small stone step and right onto the pool bank. Cross the water pool, jump left onto the high central roof, and climb onto the top-right walkway. Hold purple.
Take Fireboy to the upper-left timer
Fireboy returns across the central roof, jumps left onto the high middle roof and crosses the gap to the left roof. Drop around its outside edge and walk right onto the green plate. Keep Watergirl on purple until Fireboy is ready.
Make both return trips together
Fireboy leaves green, walks left up the slope, jumps right onto the left roof, then drops through the narrow gap to the yellow plate beside his lava pool. At the same time, Watergirl leaves purple, goes left around the end of the top walkway, drops to the central roof, and jumps right onto the pink plate.
Wait for the crossing to freeze
Keep Fireboy on yellow and Watergirl on pink. While the green and purple timers remain active, all four panels move out of the cold beam. Wait until the large bottom pool freezes. It stays frozen when the controls are released.
Bring Fireboy across the ice
Fireboy returns down the left stairs to the bottom, crosses the frozen central pool, and continues right through his lava pool. Watergirl can wait on pink while he collects the diamond.
Collect the shared diamond
From the far-right side of the lava pool, Fireboy jumps left onto the small sloping roof. Walk towards its upper-left end, rise into the opening above, then steer right into the diamond chamber. Collect the diamond at the far right.
Return Watergirl to the left exit area
Watergirl drops around the left end of her pink ledge, crosses her water pool and drops down the small outer steps to the bottom. Cross the frozen central pool to the left, then continue through her small water pool towards her exit.
Finish at both exits
Fireboy leaves the diamond chamber through its open floor, drops around the outside of the little roof and walks left through the lava to his exit. Watergirl continues left to her matching exit. 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.

If you get stuck
Check the unfinished objective
Count the ring-marked diamonds still visible. All 1 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.
