if someone can’t do Sync for the save files, what i did for android was hook up my phone to my pc. I took the save files from it, copied and saved them to my pc. Then just transferred the files on the pc to the new apk.
I'd love to support on subscribe star, since I can't on steam. But I am not familiar with it, is subscribe star like patreon where I have to do a monthly payment to get access to the latest build until it is finished? Ah, I wish there was a one time payment for android build like steam...
