If you are using joiplay,see where the game folder is located and simply move the save folder to the newer version game folder.
If you are using an apk(not sure of there is an official one) the save folder will be located in Android>data>superhuman(name might be slightly different) copy the save folder and paste it somewhere else. Install the new version and repaste the save folder by Android>data>superhuman
Newer androids might block you from accessing the Android>data files.search for a tutorial to get around this.Shizuku and ZArchiver worked for me
