Two original asset sets for a platformer, made with the ritmo-pixel-art skill, the art direction, effects, and platformer research (#157, #156, #151), and ritmo-tools (pixel lint, pixel render, fx check/look/render). Repo-only: everything lives in packages/core/genres/, which is not published. Each set is drawn by its own deterministic make.py (Python + Pillow).

Set one: Celeste scale (PLATFORMER-ASSETS.md, platformer-assets/)

• 320×180 screen, 8×8 tiles, 16×16 player frames (8×12 hitbox).
• 28 colours from Endesga 32, at most 16 per asset; moon light from the upper left; outlines by plane.
• The player is the only red; the scarf is gold while a dash is ready and blue once spent.
• Four looping backdrop planes, a foreground, a 47-tile blob autotile with a mask map, one-way plank, spikes, decorations.
• Player idle, run, jump, fall, dash, wall slide, land; fruit, spring, checkpoint; dash, dust, collect effects; a mockup.

Set two: Metal Slug scale (PLATFORMER-ASSETS-DETAILED.md, platformer-assets-detailed/)

• 384×216 screen (16:9, whole-number scaling), 16×16 tiles, 48×48 player frames (about 40 px tall, 12×34 hitbox).
• 60 colours of AAP-64 with 5–6 steps per material, at most 32 per asset; sun from the upper right; selective outlines.
• A jungle over industrial ruins: four backdrop planes, palm foreground, the same 47-tile autotile with materials, steel catwalk, spikes.
• The player is posed as a puppet (fixed limb lengths): idle 6, run 8 with arm swing, jump 3, fall 2, dash 3, wall slide 2, land 2. A backpack cell shows the dash.
• Cog collectible, spring, checkpoint beacon, a beetle enemy, effects, a mockup, and side-by-side comparisons with set one.

Tool gaps found

• pixel sheet cannot cut a regular grid (--frame 16x16); frames that touch merge.
• pixel render always writes PNG, SVG and preview, and doubles the suffix in its default name.
• pixel lint has no accept list for deliberate single pixels, no notion of a composed scene, and one colour limit for every asset.
• Nothing for tiles (loop, seam, autotile checks) and nothing checking a sheet's frames against each other (feet on one row).
• No scene-level contrast check, no palette swap, no contact sheet for sprite animations; fx takes palette names while sprite sources take hex, and flags near-duplicates in the source palette with no palette-wide accept.

Weak spots

• Set one: the player is stiff, the terrain interior flat, the mountains plain.
• Set two: hands cover the face in some poses, the head stays upright in the dash, the terrain blocks repeat visibly, the canopy reads as piles of balls, the spring reads as a drum.
• Nothing has been checked on a phone or in a running game.
