I have a problem every time I download a new version of the game on Android. When I launch the game every time I downloaded it, I always find a save of version 0.2.0, even though I had a save of version 0.2.5. The other saves are deleted.
Uh... This shouldn't happen in normal circumstances and I 100% have my previous saves with each mobile update. Ensure that you are installing the new apk as an update. + it can be worth checking your security software because I'm not a certified developer for Android and some sec packages are allergic to this.
Still, it's weird that you have 0.2 saves only. Can you make a new save in a different slot at all inside a version? If you can, then this means they aren't deleted, but stored in a different folder for reason. Maybe different profiles for different users? Also, it may be worth a shot making a manual download and not using the auto-update from Jenkins or whatever that Itch client is called.
