# Lil' Critters

A 2D platformer designed by **Isaac (age 6)**.

> Four woodland critters on a mission to get home. Each round you control a different critter with a different ability and a different threat to overcome.

That URL 302-redirects to the canonical SKILL.md (with sha256 verification, all relative links to reference docs, templates, and scripts working from the same origin). One paste = full playbook.

## The characters

| # | Name | Ability | Threat |
|---|---|---|---|
| 1 | Ant | pinchers | (anteater appears) |
| 2 | Grasshopper | chirps that make predators dance | Bird |
| 3 | Blue Jay | dive bomb (explosive!) | Eagle |
| 4 | Squirrel | flying squirrel | (acorns) |

## The levels

| # | Setting | Goal | Action |
|---|---|---|---|
| 1 | Base of Tree | Ant Mound | Collect leaves |
| 2 | In a field | Daffodil | On the run from a bird |
| 3 | Top of house | Nest | On the fly from an eagle |
| 4 | Nest | Hole in Tree | Collect acorns |

## How to play

- **Keyboard:** ← → to move, ↑ or Space to jump, X to pinch
- **Xbox controller:** Left stick to move, A to jump, B to pinch
- **F or Select:** Fullscreen
- **R:** Play again after winning

When the anteater appears, hide behind rocks or trees. The HUD shows "🤫 HIDDEN" when you're safe. The eye flashes red right before an ultraslurp — that's your dodge window. Sneak out when the tongue swings away, then press X to pinch and defeat it.

## How it was made

The art is hand-drawn by Isaac on paper, then photographed and processed via the [kid-game-builder](/.well-known/agent-skills/kid-game-builder/SKILL.md) skill — a public Claude Code skill capturing the paper-to-playable pipeline. Tech stack: HTML5 Canvas + vanilla JS, deployed as a Cloudflare Worker.
