Step-by-step walkthrough
Collect the two upper diamonds
Fireboy starts at the top RIGHT; Watergirl starts at the top LEFT. Follow the starting ramp inward, then jump INWARD across the opposite-element pool. This jump collects the high diamond near the ramp. Continue to the dry inner ledge for the second matching diamond.
Cross the goo and descend on the far side
From the dry inner ledge, jump across the central purple basin: Fireboy goes LEFT and Watergirl goes RIGHT. Follow the opposite shelf outward through your matching elemental pools. Walk off its outer end near the wall and let the landing settle on the slope below. Follow that slope inward for the next matching diamond.
Climb the outer zigzag
Continue off the slope into the safe bottom corner. Jump OUTWARD from the bottom floor onto the low wall ledge, then step inward along its crest and jump INWARD onto the next sloping ledge. That jump collects the fourth matching diamond. Move a little farther up the slope and jump OUTWARD onto the upper wall slope again.
Reach the base of the central pillar
Follow the upper wall slope inward and drop back into the dry bottom corner. Walk toward the bottom goo and jump INWARD onto the small floating stone shelf above it. Move to the shelf’s inner tip, jump straight UP, then steer inward near the peak to reach the central pillar’s broad base. Both heroes must stay clear of the long purple basin below.
Climb beside the pillar
From the base, stand near its outer edge. Jump straight UP and steer OUTWARD near the peak to land on the side shelf. This collects the diamond above that shelf. Move to its pointed inner tip and jump INWARD onto the narrow top of the central pillar. Rising before steering avoids the underside of the shelf.
Collect the two central diamonds
Cross the pillar’s top toward your own side: Fireboy goes RIGHT; Watergirl goes LEFT. Collect the matching diamond beside the crest, then drop straight down onto the base on that side for another matching diamond. Wait for the landing before moving farther outward.
Descend to your own exit
Walk outward off the base and steer onto the small floating shelf below, collecting your eighth diamond. Jump OUTWARD across the remaining goo to dry ground, then enter your matching bottom exit. Both heroes finish together. All sixteen diamonds are optional, but this route collects them all. If you miss an upper diamond after descending, restart for a perfect clear; if you miss a climb and land safely, return to the ledge tip and rise before steering.
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.

Level questions
How do you finish The Split Descent?
Jump inward across the opposite-element upper pool and the central goo, then descend on the far side. Climb the outer zigzag and central shelves before returning to your own bottom exit. Either hero can go first. Bring Fireboy to the orange exit in the lower right and Watergirl to the blue exit in the lower left. Both heroes must be at their own doors together. The 16 unmarked diamonds are optional; collect every diamond for a perfect clear.
How many diamonds are required in The Split Descent?
16 diamonds: 8 for Fireboy and 8 for Watergirl. None are required to finish. 16 unmarked diamonds are optional collectibles for a perfect clear.
Which hazards are in The Split Descent?
2 orange lava pools (middle left), 2 blue water pools (middle right), and 2 purple goo pools (middle center and lower center). Fireboy can enter orange lava; Watergirl must avoid it. Watergirl can enter blue water; Fireboy must avoid it. Purple goo defeats either hero. If either hero falls into a dangerous pool, both players restart the level.
Does The Split Descent need a partner to hold a switch?
There are no levers or pressure plates in this room. Each hero can follow their own route, but both matching exits are still needed to finish.
