i had the app, and then I deleted it. I recently gained interest in it again so I got the app, but it made me start over from level 1. Help I don't want to do all those levels again!
Some games will store your saved games in the cloud so that when you re-install the game, your progress won't be lost. However, many games simply don't save your data and you have to start from scratch. This is the fault of the developer not allowing for it. There is nothing you can do, unfortunately, except to contact the developer of the game and ask them to support cloud backup in a future release.
