Mochi’s Adventure

The first-party production platformer, installed with its real atlas, background, level flow, parallax, collectibles, enemies, and checkpoints.

An atlas is a rendering contract

The atlas turns one image into a library of source rectangles. The game maps those rectangles onto characters, tiles, items, and effects while the camera and parallax layers establish depth.

This is the real Arcade document and runtime, not a visual imitation. Package files are embedded inside the frame so the production remains local and deploys as one HTML file.

JavaScript is off. The production frame still contains the complete source and a no-script notice; gameplay itself needs JavaScript, while all case-study text and credits remain available.

What it demonstrates

Atlas coordinates as a compact asset API.
Tile collision, character state, camera follow, checkpoints, and level progression.
Two production images and self-hosted fonts embedded as data URIs.

Provenance note: Installed from ~/sanzcloud/projects/arcade/site/games/mochi-adventure/index.html. Copied the full production document; inlined its atlas, background, and self-hosted OFL fonts; removed only telemetry.
