Step-by-step walkthrough
Move Watergirl beyond the starting barrier
Send Watergirl right through the upper crystal pair and back until she emerges to the right of the crystal on the starting platform. Collect the blue diamond near that platform’s right end, then let her drop onto the walkway below. Leave her safely on the right side of the purple barrier. Raising that barrier also closes the starting corridor, so do this before Fireboy operates its lever.
Fireboy opens the left passage
Fireboy follows the upper crystal pair to the upper-right walkway and collects its red diamond. Drop around the walkway’s right end onto the passage below and collect the next red diamond while heading left. Walk through the purple lever to raise the barrier. Return through the upper crystal pair, drop off the right end of the starting platform and follow the now-open lower passage left.
Use the floor pair from the left shaft
Fireboy collects the red diamond near the left wall, then descends into the narrow outer-left shaft for the lower red diamond. Fall into its floor crystal. The opposite crystal sends him upward in the outer-right shaft. Steer left as he rises above the dividing wall and land on the inner stone ledge. Keep away from the long purple pool along the bottom.
Explore the angled pair and lower islands
Use the sloping middle passages and the angled crystal pair to reach both sides of the left inner chamber. Fireboy collects the middle red diamond beside the upper angled crystal, the red diamond above the right-hand middle walkway, and the red diamonds beside the two lower islands. Jump between the stone islands over the purple pool. Climb the right-hand steps into his red exit.
Watergirl restores the left passage
Watergirl now explores the upper-right branch for its blue diamond, then follows the passage left to the purple lever. Walking into it turns it off again; use interact once beside the lever to raise the barrier again before continuing. Use the upper pair and the opened passage to collect the blue diamond on the upper-left walkway, then drop to the next left-hand shelf for its blue diamond.
Collect Watergirl’s lower diamonds
Use the outer-left shaft and floor pair to reach the right side, collecting the blue diamond in the right shaft during the upward flight. Follow the middle passages to the angled pair and collect the blue diamond on the small left ledge. Jump to the lower-left island for its blue diamond, then climb the inner shelves for the blue diamond below the sloping central wall. Move clear of a receiving crystal before entering it again when changing branches.
Reach the blue exit
From the inner shelves, use the angled passage and sloping stone path to reach the blue door beside the central wall. Fireboy waits in the right-hand red door. Both matching exits and all eight diamonds of each element complete the room.
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.
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.
