Step-by-step walkthrough
Collect the two starting diamonds
Fireboy starts at the top RIGHT and walks left down the ramp; Watergirl starts at the top LEFT and walks right. Collect the two matching diamonds along each ramp. Stop on dry ground before the purple goo.
Jump inward and drop through the center
Fireboy jumps LEFT across the upper goo; Watergirl jumps RIGHT across the other basin. Land on the dry inner tips, then walk into the narrow central gap. Let the fall settle on the crest of the broad shelf below. Purple goo is dangerous to both heroes.
Collect the opposite-side row
From the middle crest, Fireboy follows the shelf LEFT for three orange diamonds; Watergirl follows it RIGHT for three blue diamonds. Continue all the way up each outer tip to collect the diamond beside the wall before dropping farther.
Drop onto the outer side ledge
Walk off the outer tip toward the nearby wall. Fireboy drops onto the LEFT side ledge and walks right across it; Watergirl drops onto the RIGHT ledge and walks left. Collect the matching diamond on the ledge and stop at its inner edge.
Jump back toward the center
Fireboy jumps RIGHT from the left ledge onto the sloping central shelf; Watergirl jumps LEFT from the right ledge. Walk inward across that shelf to collect the matching diamond near its center.
Descend on the other side
Fireboy continues RIGHT off the central shelf, collecting the orange diamond during the drop. Watergirl goes LEFT for the blue diamond. Let the landing settle, then continue outward across the lower ledge to collect the diamond near the wall. Walk off its outer edge to reach the bottom floor.
Follow the bottom floor to your exit
Fireboy heads LEFT from the bottom-right corner; Watergirl heads RIGHT from the bottom-left corner. Each collects two final diamonds along the uneven floor. Enter the orange door just RIGHT of center and the blue door just LEFT of center. All twenty-two diamonds are optional, but this route collects them all. If an upper diamond was missed after a one-way drop, restart for a perfect clear.
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 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.
