-# LUNA-1: Pink Unicorn Game — Project Scaffolding
+# LUNA-2: Character Controller — Jump, Gallop, Trails
 
-Starter project for Mackenzie's Pink Unicorn Game built with **p5.js 1.9.0**.
+Starter project for Mackenzie's Pink Unicorn Game built with **p5.js 1.9.0**, implementing the core character controller.
+
+## Controls
+
+| Input | Action |
+|-------|--------|
+| Tap / Click | Move unicorn toward tap point |
+| Spacebar | Jump (when grounded) |
+| Proximity | Long distances trigger gallop speed boost |
+
+## Features
+
+- **Physics**: Jump with gravity affecting vertical movement
+- **Gallop**: Speed increases when far from target; dust particles trail behind
+- **Movement sparks**: Trail particles (sparkles) follow unicorn path; more frequent during gallop
+- **Floating islands**: Multiple platforms at varied heights
+- **Collectibles**: Crystals with particle burst feedback
+- **Touch-friendly**: Works with mouse and touch
+
+## Technical Details
+
+- p5.js loaded from CDN (no build step)
+- Easing horizontal movement (`lerp`) with gallop factor
+- Vertical movement simulation with gravity and ground collision
+- Particle systems for trails, dust, and collection bursts
+- `colorMode(RGB, 255)`; pink/unicorn palette defined in code

 ## Verification
 
-Open in browser → canvas renders a white unicorn with a pink mane. Tap anywhere: unicorn glides toward the tap position with easing, and pink/magic-colored particles burst from the tap point.
