I need to scope this down to an MVP. A full MOBA with 5v5 multiplayer, champion roster, abilities, items, jungle, towers, minions, and 30-40 minute matches would require thousands of lines and a backend server.

**MVP Scope - Single HTML File:**
- **1v1 (not 5v5)** - Two players, simplified team mechanics
- **One lane** - Top lane with towers, no jungle/objectives
- **2 champions** - Tank vs Mage, different stats/playstyles
- **2 abilities each** - Basic attack + one special ability (no ultimates)
- **3 items** - Simple stat boosts (damage, health, speed)
- **Core mechanics**: Move, attack, level up, buy items, destroy tower → destroy base
- **10-minute matches** - Fast-paced core MOBA loop
- **Top-down view** - Smooth camera following player

This captures the essential MOBA experience: lane control, champion combat, item progression, and base destruction. We can add more champions, abilities, and lanes later.
