Pure polish on the one shared slime-family defeat path, so it lifts every level at once. - A stomped foe now FADES OUT over its ~700ms linger (blendLevel ramps 0 -> ~96) instead of blinking off. The sprite is a button (b2kSpriteNew returns its long id), so blendLevel fades its icon; reset to 0 before the sprite is freed so a reused control is never born transparent. The window is short and only a stomped foe or two ever fade at once. - The spook foes show a proper DEAD pose instead of a hit-flash: the bat bat_hit.png -> bat_dead.png, the mimic grassBlock_hit.png -> grassBlock_dead.png (same sheet as the live foe, so always present when it is). The slimes/snail/block-slime already played their _flat/_shell/_rest squash poses, and the telegraphing foes already idle on rest frames (barnacle_*_rest, block_rest, bat_hang), so this is the remaining gap. Example-side only (no Kit change, no harness bump). Static gates clean, audit 0 findings. Needs the OXT pass (the fade reads, the dead poses show). Second skins + a defeat poof are optional follow-ups. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X92APxUJUMue3bAzXiX9V2
Four little pale dust motes now arc out of a squashed foe - the classic stomp poof, on top of the fade + dead poses already in Phase D. Built on the proven pooled-debris pattern so nothing is created mid-game: pfMakeDustPool pre-spawns eight tiny b2kSpawnBall bodies parked off-world (every level, after the hero exists so the no-collide is valid); pfDustBurst flings four of them out of the squash point (captured from the foe's body before it is removed); pfTickDust re-parks them ~0.5s later. The motes ARE the art - small light balls, no new frames - and b2kSpawnBall births them in the camera group, so they scroll with the world and b2kMoveTo handles the scroll for free. The burst fires from pfSquashSlime (the kill/dissolve path; snails shell via their own case, no poof on a mere shelling). Example-side only (no Kit change, no harness bump). Static gates clean, audit 0 findings. Needs the OXT pass (the poof reads at a stomp). A defeat "pop" + the second skins remain optional follow-ups.

Two more juice items on top of the fade + dust-poof. DEFEAT POP: the squashed art now also arcs UP (~50px, ease-out) as it fades, instead of just dissolving in place. The squash point is captured in pfSquashSlime (gSlimeDeadX/Y) and the linger in pfTickSlimes drives the pop + the blendLevel fade off one elapsed clock. Snails shell via their own path, so only true kills pop. SECOND SKINS (bestiary variety): - pfMakeCritter gains an optional trailing pSheet (default "foes"), so it can field the spooks-sheet .png slime skins. - A GREEN and a BLUE slime (slimeGreen/Blue, spooks) reskin two L1 slimes, gSpooksOK-gated (a normal foes slime without the sheet, so no downgrade to a bare box for the no-spooks case). - The RING worm (worm_ring_*, native foes - always present) reskins L2's worm. New "wormring"/"slimegreen"/"slimeblue" anim defs. tools/audit-platformer.py: two same-index makers are a conditional reskin (if gSpooksOK / else), one foe not two - skip the patrol-overlap warn for same-index pairs. Back to 0 findings across 7 levels. Example-side only (no Kit change, no harness bump). Static gates clean. Needs the OXT pass (the pop reads; the green/blue/ring skins show + are aligned; slimeBlue's walk pair may want a tweak).

A new slime-family kind "snake" with its own tick: it crawls the floor and AUTO-REVERSES at a pit edge or wall, so you place it without hand-tuning a band. - pfTickSlimes gains a "snake" case: one b2kOverlap floor-probe AHEAD-and- BELOW the body each frame (sits past the snake's own box, so empty = a ledge -> flip); pMinX/pMaxX are the outer safety bound. Gravity keeps vy, so it hugs the floor. - Kind "snake" falls through to the classic stomp verdict (top = squash, side = hurt), so it is stompable and the Phase-D defeat juice (dead pose, poof, fade, pop) carries it for free. - pfMakeSnake pIdx,pX,pMinX,pMaxX,pTopY,pSkin picks plain / snakeLava / snakeSlime (all spook-sheet .png art), self-gates on gSpooksOK, and reuses pfMakeCritter's new sheet param. New snakewalk/snakelava/ snakeslime anim defs. Deployed: a LAVA SNAKE on L4's lava-pit bank (turns at the chasm and the lava) and a plain SNAKE on L3's second ice platform (turns at the spike pit), both clear of the other ground foes. Example-side only (no Kit change, no harness bump). Static gates clean, audit 0 findings. Needs the OXT pass (the slither reads, snakes turn at edges and never fall in, art aligns). snakeSlime + more placements + the audit's pfMakeSnake branch are the next Phase-E steps.

Replace L4's collapsing bridge (which never read right) with a rising lava serpent and rework the lava beat: - Widen the lava pit to a 512px chasm (2944..3456, was a 192px strip), crossed in two ~160px hops over a new middle stepping-stone (pf_lavastep, deck y490). Bank slabs + tiling + sign/grass adjusted. - New pfMakeLavaSerpent / pfTickLavaSerpent: a bodiless snakeLava sprite that rises out of the lava, arcs across on a sine path and sinks back in, peaking at the stepping-stone so it contests the rock you must land on. Created before the lava tiles so the y576 tile row occludes its submerged body (reads as rising from / sinking into the lava), with a visibility toggle backing the no-tile fallback. The head's strike zone is a proximity-poll knockback (the saw rule, gotcha 16). Self- gates on gSpooksOK; absent the sheet the pit is a plain two-hop gap. - Remove the collapsing-bridge maker/tick/globals wholesale (only L4 used it). Audit drops its collapse tracking; pf_lavastep registered as a landing surface. - pfMakeSnake is now the plain low crawler only (no pSkin variant); the tall rearing snakeLava/snakeSlime art is the serpent above. L4's broken snakeLava call removed; the approach keeps a plain slither snake. - Grounding fix: the spook slime/snake skins fill their frames edge to edge (zero padding, measured against enemies.png), so feet-on-ground is the plain geometric pFullH/2 - frameH*0.9/2, not the FOES soft-bottom sink that floated them ~9px. Needs an OXT pass to confirm to the pixel. Static gates clean (no smart quotes, handlers/blocks balanced, kit in sync); audit-platformer 0 findings across 7 levels.

…on crate)
Two L4 fixes from the OXT pass:
- The lava serpent never rose. pfTickLavaSerpent computed its emergence
with sin(kPI * tP), but kPI is declared ~900 lines LATER in the script
(every other kPI use is after its definition; this was the only forward
reference). OXT's stricter compiler leaves a forward constant ref
unresolved, so the term collapsed to 0 every frame: tEm stayed 0, the
head y stayed at the lava surface, and the tick took its "submerged,
stay hidden" branch forever. Use the literal pi instead - the serpent
now actually rises, crosses and sinks.
- The fire slime ("the lava creature") jammed against the powder-keg
crates: its patrol band ran to 3600 (body right edge ~3624) into the
crate pyramid at 3644. Pull the band back to 3484..3560 so it patrols
the bay clear of the crates.
Static gates clean; audit-platformer 0 findings across 7 levels.

What
Carries the platformer through Phase D (defeat-animation juice) and Phase E (snakes / the slither beat) of the asset-expansion plan, all example-side — no Kit change, no harness bump.
Phase D — defeat juice (one shared slime-family defeat path, so it lifts every level)
blendLevel0 → ~96) with an ease-out pop, instead of blinking off. Reset to 0 before the sprite is freed so a reused control is never born transparent.bat_hit→bat_dead, mimicgrassBlock_hit→grassBlock_dead).pfMakeDustPool/pfDustBurst/pfTickDust, the pooled-debris pattern, nothing created mid-game).worm_ring_*,slimeBlue/Green*) via a new sheet param onpfMakeCritter.Phase E — snakes & the serpent pit
snakekind + slither tick — a floor crawler that auto-reverses at a pit edge or wall (one floor-probeb2kOverlapper frame). Stompable like a slime; the Phase-D juice carries it for free.pfMakeSnakeis the plain low crawler; deployed on L3 and L4's lava-pit approach.snakeLavaserpent rises out of the lava, arcs across and sinks back in on a sine path, peaking at the stone so it contests the rock you must land on (pfMakeLavaSerpent/pfTickLavaSerpent). Created under the lava tiles so its submerged body is occluded; the head is a proximity-poll knockback (the saw rule). The collapsing-bridge maker/tick/globals were removed wholesale.enemies.png), so their bind offset is the plain geometricpFullH/2 - frameH*0.9/2, not the FOES soft-bottom sink that floated them ~9px.Verification
