What am I doing here?Radiance Layer is a large late-game zone built around light, shadow, and Synthetic Sun puzzles. Snake Bananza unlocks in Sublayer 1201, providing high-jump and slow-fall utility. Clear by sublayer bucket — 1200 through 1204 — and separate light-state-dependent collectibles from standard visible gems.

What Bananza power matters here?Snake Bananza unlocks in Radiance Layer, Sublayer 1201. Use it for high-jump, slow-fall, and elevated-platform access.
All four earlier forms (Kong, Zebra, Ostrich, Elephant) remain available.
Do not mark every high ledge as Snake-gated without a verified source note.

Sublayer 1200

Radiance entry and sublayer orientation

  1. Tasks: Use Sublayer 1200 as the entry bucket and immediately separate light-route notes from standard visible collectible notes.; Write skipped items by sublayer number before adding landmark detail.; Clear the main route forward before attempting every puzzle or buried reward.
  2. Bananza power or form: Snake Bananza is not yet available in Sublayer 1200. Mark elevated or slow-fall-dependent routes for a return pass after the unlock.
  3. Boss or major encounter: None verified for this sublayer. No boss is confirmed for the Radiance entry route. Radiance spans several sublayers; do not try to clear everything in one pass.
  4. Collectibles: Visible Banandium Gems near the entry route and accessible dune caves.; Light-route gems should be tracked separately from standard visible items.
  5. Cleanup before leaving: Advance toward the Snake Bananza unlock in Sublayer 1201.; Keep separate notes for Synthetic Sun puzzle states and shadow-path states.
  6. Unlocks next: Sublayer 1201 and the Snake Bananza unlock route.
02
Sublayer 1202

Synthetic Sun, dune caves, and Snake Bananza use

  1. Tasks: Use Snake Bananza (unlocked by now) for elevated platforms, vertical climbs, and air-control checks.; Group cleanup by visible gem, Synthetic Sun puzzle, ceiling traversal, lava removal, dune cave, Growtone task, battle route, or shadow path.; When light state changes open or close a route, record the state change before the reward.
  2. Bananza power or form: Snake Bananza is the primary form for Radiance Layer's height and air-control challenges. Use it when the route clearly supports high-jump or slow-fall. Return to earlier Radiance sublayers with Snake after the unlock.
  3. Boss or major encounter: None verified for this sublayer. No boss is confirmed for Sublayer 1202. Synthetic Sun and shadow puzzles require tracking the light-state change, not just the collectible location.
  4. Collectibles: Banandium Gems tied to Synthetic Sun puzzles, dune caves, and shadow paths.; Leave exact hidden directions to the collectible map.
  5. Cleanup before leaving: Do not mix dune-cave rewards with Synthetic Sun puzzle rewards; they need different return notes.; Carry a clean sublayer-bucketed list into Sublayer 1204.
  6. Unlocks next: Sublayer 1204 shadow path and the route to Groove Layer.
03
Sublayer 1204

Shadow path and Groove Layer transition

  1. Tasks: Complete Sublayer 1204 shadow-path cleanup and confirm the main Radiance route is done.; Separate post-story or gear-dependent checks from first-return cleanup.; Continue to Groove Layer once the transition is available.
  2. Bananza power or form: All five Bananza forms are available at this point. Snake is most relevant for Radiance shadow paths; use other forms where the route specifically asks.
  3. Boss or major encounter: None verified for this sublayer. No boss is confirmed for Sublayer 1204. This is a shadow-path cleanup pass and transition zone, not a story gate.
  4. Collectibles: Remaining Radiance Banandium Gems in the shadow path and Sublayer 1204 sections.; Any post-story or gear-dependent items should go in a return list.
  5. Cleanup before leaving: Confirm each skipped Radiance reward has a sublayer number in your notes.; Keep Radiance notes separate from Groove Layer notes.
  6. Unlocks next: Groove Layer (Layer 14) and the music-restoration route.

Route Walkthrough

4 Route Steps
01
Sublayer 1200

Start Radiance With Clear Sublayer Buckets

  1. Use Sublayer 1200 as the entry bucket and immediately separate light-route notes from ordinary visible collectible notes.
  2. Radiance spans several sublayers, so write skipped items by sublayer number before adding landmark detail.
  3. Clear the main route forward before attempting every puzzle or buried reward.
02
Transformation

Track Snake Bananza as the Main Utility Form

  1. Source guides document Snake Bananza as a Radiance Layer unlock with high-jump and slow-fall utility.
  2. Use Snake notes for elevated platforms, vertical climbs, and air-control checks where the route clearly supports that form.
  3. Do not mark every high ledge as Snake-gated unless the source record confirms the requirement.
03
Puzzles

Separate Synthetic Sun, Lava, and Shadow Checks

  1. Group cleanup by visible gem, Synthetic Sun puzzle, ceiling traversal, lava removal, dune cave, Growtone task, battle route, or shadow path.
  2. If light state changes open or close a route, record the state change before the reward.
  3. Leave exact hidden directions to the collectible map until each subroute is verified.
04
Exit

Carry a Clean List Into Groove Layer

  1. Before leaving Radiance, confirm the main route is complete and each skipped reward has a sublayer number.
  2. Separate post-story or gear-dependent checks from first-return cleanup.
  3. Continue to Groove Layer once the transition is available.
