Step-by-step walkthrough
Collect the diamonds near the start
Leave one hero safely at the bottom while the other explores. Collect Fireboy’s red diamond and Watergirl’s blue diamond along the bottom corridor. The purple wall pair connects the bottom corners. From the right side, jump onto the sloping walkway above the starting area; Watergirl collects its blue diamond.
Open the green wall pair
Climb left along the walkway and pass the green lever to switch it on. Fireboy collects the red diamond near the left end. Jump into the green wall crystal to emerge beside the upper-right walkway. Keep moving left as you arrive. Collect Watergirl’s blue diamond along the upper shelf and Fireboy’s red diamond on its higher left end.
Move the original stone box
Reach the shelf with the stone box and Fireboy’s red diamond. Get onto the left side of the box, then push it right into the pale-blue crystal. The box appears beside the matching crystal on the lower-right walkway. Pause before following it, then jump into the entrance so you arrive high enough to get onto its right side.
Leave the box on the yellow plate
Push the box left until it rests on the yellow plate. The tall yellow barrier withdraws into the floor. Stop pushing while the box still covers the plate. Jump upward before steering left over the box; this keeps it in place. Watergirl collects the blue diamond farther left on this walkway.
Reach the orange pair
Walk left through the opened barrier and jump onto the small island below the orange crystal. Collect Fireboy’s red diamond on its right side and Watergirl’s blue diamond on its left side. Enter the orange pair to reach the upper-left exit chamber.
Collect the exit-chamber diamonds
Use both sides of the orange pair to reach Fireboy’s red diamond on the left and Watergirl’s blue diamond on the right. Move away from a receiving crystal before turning back into it. Return to the matching exit after collecting all six diamonds of your element.
Bring the waiting hero through
Follow the same lower and upper passages with the second hero. Leave the box on the yellow plate. If passing the green lever turns the wall pair off, walk clear and pass it again to turn it back on before using that pair. Reach the matching door with all twelve diamonds collected.
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.

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.
