Second of the level-length audit pass: Scorched Dunes grows from 4,200px / 12 coins / 3 foes to ~6,400px and 24 coins, keeping Act 1 verbatim and appending two desert acts across three thorn pits. ACT 2 - a darting fly (mover with a hurt box), a SECOND dune a sand boulder rolls DOWN at you (it re-parks at 4160, so the bank you land on after PIT2 stays safe), a high one-way sand-cloud route, a fire critter (spike-type: no stomp) and a second frog. ACT 3 - a treasure mimic, a second fly, a final sand-cloud route and a homeward snail to the summit steps + flag. Three checkpoints now (using the fixed multi-checkpoint path). Desert variety stays thematic - flies, a rolling dune boulder, fire slimes, a buried-treasure mimic - no cave creatures. Also back-fills the CHANGELOG with the multi-checkpoint fix that shipped in the previous PR without a changelog note. Example-side only (no Kit change, no harness bump). Static gates clean; the geometry audit caught a summit coin overlapping the flag (fixed), 0 findings across all 7 levels. Needs the OXT pass for feel/spacing.

The vertical climbing tower, made to really pop for the length pass. It roughly doubles in height (1,280 -> ~2,300px, 8 -> 16 ledges) and goes from 8 coins / 2 spinners to ~22 coins / 2 bonus gems and a real bestiary. Variety chosen to work in a VERTICAL shaft. Bats, ghosts, snails and mimics all hardcode a horizontal ground-y (the bat seeks y450, the ghost clamps to 220..540, the snail builds its body at y544, etc.), so they were ruled out. The makers that take an explicit surface-y ride the one-way ledges fine, so the keep fields: - FIVE sweeping spinners guarding the climb gaps, each verified standing-safe on both adjacent ledges (hero half-height 38, hurt 28); - a stationary HALF-BLADE (pfMakeSpinner pHalf) on the final ledge; - three WARDENS on the wide "fight" ledges - a slime to stomp, a hopping frog, and a spike slime to dodge (no stomp on the spikes). pfDressWall tiles the taller shaft; the windows/torches climb it. Example-side only (no Kit change, no harness bump). The geometry audit skips vertical levels, so the spinner safety and ledge spacing were hand-verified; script gates clean, L1-L6 still 0 findings. Needs the OXT pass for the vertical-only checks (walkers resting on the one-way ledges, the spike-slime leap to L14, blade timing, the taller wall build).

Phase C slice 3, part 1 (the multi-key half). pfMakeKeyDoor was single-instance - it stashed the door + its key state in shared globals (gHasKey/gDoorX/gLockSpr/...) that each call overwrote, so a level could have exactly one door. It now appends to a per-door table indexed 1..gDoorN, and the hero carries a SET of keys instead of a single boolean: - gKeysHeld is the comma-list of colours held (HUD: [KEYS yellow,blue]); - each key tags itself uPfKeyWord = its colour (Word, not Colour - the stem 'colour' is an engine property, gotcha 2) and rides the shoulder, fanned out by held-count when you carry several; - pfTickDoors loops every door; the matching held key opens it and is CONSUMED, so each key opens exactly its own colour. Single-door levels (L3's red door) build as door #1 and behave as before. L2 "The Works" now ends on a TWO-KEY lockgate: a yellow key on the main run, a blue key up on the hop clouds, and a double door before the flag. L2 also gains coins to 24 (was 19), closing the level-length audit's last loose end. Example-side only (no Kit change, no harness bump). Static gates clean; audit 0 findings across all 7 levels. The floor switch -> gate half of slice 3 lands next. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X92APxUJUMue3bAzXiX9V2
…rt 2) The floor-switch half of Phase C slice 3. pfMakeSwitchGate plants a floor/ledge switch (switch_<colour>) and the coloured kinematic gate (block_<colour>) it opens. Unlike pfMakeGate's momentary pressure pad it LATCHES: step on the switch once and the gate rises out of the way for good. pfTickSwitchGates polls only-moving-bodies (the ground slab never reads as pressed), drives the kinematic gate up on change, and once it settles open gSwDone short-circuits the tick to one compare/frame. L2 "The Works" gets a GREEN switch-gate: the gate bars the way into the crusher alley until you climb to the third-bay cloud and press the switch up there - a "find the switch" beat (skip it and the closed gate sends you back to look). Keys + switch are all gToysOK-gated, so a missing tiles sheet degrades to an open run. Mirrors pfMakeGate's kinematic-velocity move (write-on-change). Fixed a dangling-else in the maker (block-form the inner sprite-bind if, like pfMakeGate). Example-side only (no Kit change, no harness bump); static gates clean, audit 0 findings. Slice 3 complete - needs the OXT pass (the switch detection + the gate opening reliably).

OXT feedback: the blue door sat embedded in the goal step (level unwinnable), and the two gates were crammed together by the flag. The L2 stone vault finale was only ~220px (yellow door 5344 -> steps 5568), with no room for a second door - so the blue door at 5600 landed inside pf_plat1 (5568..5760). Extended the finale (~5,884 -> ~6,312px) into a real corridor: yellow gate (5344), a 416px stone corridor, blue gate (5760), a run, then the steps (6016) and flag (6272) - each its own beat, the gates well clear of the steps. End coins re-placed along it (L2 now 25 coins), and the grass bush that would have sat inside the stone vault moved out to 5160. Also gave the GREEN switch-gate clear air: moved it 4060 -> 4000 and retired the redundant fourth-bay snail (it jammed between the snail and the first crusher) - the switch-gate guards that approach now. Example-side only; static gates clean, audit 0 findings across 7 levels. Needs the OXT pass (the two gates open with their keys, the switch opens the green gate, the flag is reachable).

What
Second increment of the level-length / variety pass (after L6 in #60). Expands L5 "Scorched Dunes" from a single ~4,200px act into a full three-act level, with thematic desert variety.
L5 — Scorched Dunes, now ~6,400px / 24 coins / 3 checkpoints (was 4,200px / 12 / 1)
All of Act 1 kept verbatim (the dune, thorn pit, two-cloud hop, slime/frog/snail/barnacle); two new acts appended across three thorn pits:
Variety stays in-theme for a desert — flies, a rolling dune boulder, fire slimes, a buried-treasure mimic — no cave creatures.
The three checkpoints use the multi-checkpoint fix from #60 (each flag banks its own respawn x; only ever advances). This PR also back-fills the CHANGELOG with that fix, which shipped in #60 without a changelog note.
Verification
check-livecodescript.py— PASSaudit-platformer.py— 0 findings across all 7 levels (it caught a summit coin overlapping the flag; fixed)Needs the OXT pass for feel/spacing — especially that the dune boulder is dodgeable on the climb and never traps you, and the three thorn-pit checkpoints all light. L7 (taller tower + more spinners/ledges) and a coin top-up for L2 follow.
