I use Joiplay and can't open the game? Does anyone know how to fix it?
Joiplay's renpy plugin is for up to renpy verion 8.1.1 iirc for now.
This release use renpy 8.2 for what I see in it's files, so we have no way to play with joiplay for now, fellow joiplay enjoyer!
For what I read 8.2 had a lot of changes & improvements so I doubt if new renpy plugin will out anytime soon.
If device's bit old you can still install android version and write Android/data/ dir without root as long as it's not installed in 'Work profile / Secret Folder / Island' or whatever it is.
But ultimately you'll want to have rooted alt phone/tablet to easier save file transfer/backup.
