I've created a clicker game with in-app purchases featuring:

**Gameplay:**
- Click the golden coin to earn coins
- 3 upgrades: Click Power, Auto Clicker, and Multiplier
- Coins per second display and floating +coin animations

**IAP Products:**
- **1,000 Coins** - 99 credits ($0.99)
- **5,000 Coins** - 399 credits ($3.99)  
- **15,000 Coins** - 799 credits ($7.99)
- **2x Click Power** - 299 credits (permanent, doubles all clicks)
- **Auto Clicker** - 499 credits (permanent, +5 coins/sec)

The game runs in background mode so coins keep accumulating when minimized.

**Next Ideas:**
1. **Prestige System** - Reset progress for permanent multipliers and new upgrades
2. **Achievement Badges** - Unlock rewards for milestones like 1M coins or 100 upgrades
