Help/Support LDOE Lost Progress after Sideload

I downloaded Last day on earth via Sideloadly, I played it for a week, after this week I had to download the game again but my progress disappeared, how can I get my progress back?

Hello,

You should not uninstall the already sideloaded app but instead use the same Apple ID you initially used and Sideloadly will update and overwrite the app for you retaining all your app data, including save game.

Another way around this is to either use a paid Apple ID or download through the iOSGods App+ which will make Game Center work.
