a comment for XianGrim (thanks for working on this awesome game!)
One cause I found for the black screen is a save in an older version (0.1.5.3 hotfix), where the save was in the beach, and, as you know, that was changed in the newest (free) version (0.1.7.1). I know data such as exp and save location translated to the newer version since that’s what happened to me. It is possible that the new version is trying to look for the save but cannot find it because it was changed.
I’m not sure if this is the case for Android, as I am on windows.
