Guided 2D Game / vertical slice

A guided product Buildprint, not a game, engine, skill or asset-generation plugin. It turns a broad idea into an agreed small original pixel game and provides operational art, animation, world and release contracts. Brawler guidance is detailed; platformer, farming and puzzle branches adapt the same spine.

Start at BUILDPRINT.md. Intake asks sequential questions, then the builder proves a graybox and in-game art direction before scaling content. Default spend is zero. Multiplayer and public hosting are explicit scope decisions, not implied features.

Packet map

  • 00-goal.md: guided intake, large-vision warning, exclusions and decisions.
  • 01-setup.md, 02-identity.md: existing-tool/license preflight and readable pixel identity.
  • loops/: five kernel loops from graybox to frozen release review.
  • references/: genre, animation, world/tiles, provider recovery and operational QA.
  • templates/: compact agreements, asset requests, money recovery and milestone handover evidence.
  • validation/: original dependency-free Node/browser contract module, PNG decoder, loader adapter, fixture manifest and negative tests. This is a bounded starter validator, not a universal collision engine.

Check this repository packet

From the repository root, Node.js 20+:

node bin/agb.js packet check buildprints/guided-2d-game
npm run check:guided-2d-game

The second command also decodes the fixture PNG, validates the loaded manifest and runs negative tests. See validation/README.md for runtime integration and coverage limits. Do not treat synthetic fixture art as approved game art or fixture tests as a playthrough.

Start from the published packet

Use the latest repository CLI until a release includes byte-exact binary snapshot downloading; older installed AGB versions can corrupt the bundled PNG fixture. No global install is needed:

git clone https://github.com/DomEscobar/agent-buildprint
node agent-buildprint/bin/agb.js start https://agent-buildprint.com/buildprints/guided-2d-game/package.json my-game

Then give my-game/.buildprint/next-agent.md to the builder. The repository’s check:guided-2d-game also bootstraps this actual packet, compares all 33 snapshot files byte-for-byte, and validates the downloaded PNG.

Claim ceiling

No game was built, no paid generation performed, no provider plugin installed and no browser/game deployment certified by this packet. Public provider docs were inspected on 2026-09-07; volatile catalogs and protected setup must be rechecked before use. media4agents’ public API details could not be verified; that route is conditional. Independent runtime review is required before qualifying an applied game. No third-party scripts or proprietary game assets are bundled.
