Move the grapes by clicking them, and they will eventually evolve into watermelons!
[Core Rules]
1. **Movement and safety mechanism**
- Click the screen → The grapes move to the clicked position.
- **Release your finger** → The grapes stop immediately and **enter a safe state** (no touch fusion will be triggered in this state).
2. **Fusion and evolution**
- **Only touch fruits ≤ their own size while moving** → Fill their progress bar.
- When the progress bar is full → The grapes upgrade to larger fruits (final form: watermelon).
3. **Failure and settlement**
- Touch a larger fruit → Restart the current level immediately (the grapes are reset to the initial state).
- At the end of each round, the current score and the highest score in history are displayed.
