**Patient Zero** is ready. Here's what's in the MVP:

**Core Features:**
- **Isometric top-down view** with Project Zomboid-style open roofs — buildings reveal interiors when you walk inside
- **80+ zombies** that shamble, wander, and aggro on proximity — slow but deadly in groups
- **Full neighborhood map** (120x120 tiles) with houses, restaurants, a hospital, school, stores, and garages connected by roads and sidewalks
- **Health, Hunger, Thirst bars** — hunger/thirst drain over time, starving kills you
- **5-slot hotbar** + 20-slot inventory (TAB to open)
- **Lootable buildings** with location-based items: food in kitchens, meds in hospitals, weapons in garages
- **Melee combat** (bat, knife, pipe, axe) with weapon durability + rare pistols with limited ammo
- **Day/night cycle** with darkness overlay and flashlight cone
- **Blood splatters, particles, damage flash**
- **Procedural audio** via Web Audio API (hits, gunshots, zombie groans, pickups)
- **Clean start menu** ("This is how you died." tagline) and **death screen** with survival time, kills, and restart

**Controls:**
- **WASD/Arrows** — Move
- **Space/J** — Attack
- **E/F** — Pick up items
- **Q** — Use consumable (food/water/meds)
- **R** — Reload gun
- **1-5** — Switch hotbar slots
- **TAB** — Inventory

**Next Ideas:**
1. **Barricading System** — Board up windows and doors with planks to create safehouses, zombies pound against barricades over time
2. **Sound Aggro Mechanic** — Gunshots attract distant zombie hordes, creating emergent tension between using firearms vs. staying quiet with melee
