The game progress is stored on the remote server and it is downloaded to your device as soon as you launch the game with your internet connection turned on. Thus, it is impossible to delete the progress and start the game from scratch on the device you have already played the game. However, you may start playing from the very beginning on a new device in the following way:
- Install this game on any other supported device.
- Create a new G5 Friends account on it.
- Log into your newly created G5 Friends account on the device you used to play the game on, and your new game progress will be automatically transferred to it.
