Cranky Coop

A physics slingshot game. The raccoons raided the henhouse and ate every egg; the hens take it personally.

• Play locally: https://cranky-coop.localhost:8443 (Caddy serves this directory)
• Engine: Matter.js 0.20.0 from cdnjs; everything else (art, sound, levels) is hand-drawn canvas and synthesized Web Audio in game.html.

Build

game.html is the page body (also what gets published as the claude.ai artifact). ./build.sh syntax-checks the script and wraps it into index.html.

How to play

Drag the hen back from the slingshot and let go. Tap (or press Space) mid-flight to use a power. R restarts, M mutes, Esc opens the level select.

Hen	Power
Clucky (red)	None. Pure rage.
Zippy (yellow)	Dash forward. Extra damage on wood.
Big Bertha (black)	Explode, or wait for the fuse after landing.
The Triplets (blue)	Split into three. Extra damage on glass.

Raccoons come in regular, hard-hat (tougher) and the Raccoon King.

Adding a level

Append to LEVELS in game.html. build(b) gets builders that take a bottom y (base) and return the new top: b.hut(mat, x, base, w, h), b.post, b.beam, b.crate, b.hay (static platform), b.coon(x, base, type). Ground is at G = 900; the slingshot is at x = 250; keep forts within x ≈ 950–1750. Materials: wood, glass, stone. Raccoon types: coon, hat, king.
