Our game is designed in a way players cannot lose their progress easily, and thus the progress is saved on the server.

For the moment, there is no option to start a new game as there is no Game Over in the game. You can always get coins and continue playing.
 
Meow-the-way, if you use any other device, you can download the game there and start anew.

This option may appear in the future, and we surely will notify you if that happens!
