Perfect! I've created a fully functional Balloon Tower Defense game with the following features:

**Game Mechanics:**
- 🎈 Multi-layered bloons (red, blue, green, yellow, pink) with health values
- 🗼 4 tower types: Dart (basic), Tack (8-directional), Sniper (infinite range), Bomb (area damage)
- 💰 Economy system with starting money and rewards for popping bloons
- ❤️ Lives system - lose lives when bloons escape
- 🌊 Progressive wave system with increasing difficulty

**Gameplay:**
- Click a tower in the menu to select it
- Click on the game field to place towers (avoiding the path)
- Towers automatically target and shoot the furthest bloon in range
- Click "Start Wave" to begin each wave
- Earn money by popping bloons and completing waves

**Tower Abilities:**
- **Dart Tower** ($200): Basic single-shot tower
- **Tack Tower** ($300): Shoots projectiles in 8 directions
- **Sniper Tower** ($400): Instant hit, infinite range, slow fire rate
- **Bomb Tower** ($600): Explodes on impact, damages multiple bloons

**Next Ideas:**
1. **Tower Upgrades** - Add a 3-tier upgrade system for each tower with enhanced damage, range, and fire rate
2. **Special Bloons** - Introduce camo bloons (need special detection), ceramic bloons (high health), and MOAB-class bloons (massive armored balloons)
