Could it be the reason why some other games here ask for permission to access all files?

Hmm, if that is the only thing stopping it from working. Then I'd say maybe see if you can figure out a way to make it request the needed permissions. Probably not right away but maybe something worth looking into for a future update.
Maybe have it request storage and notifications permission at the very least if possible. Storage for the game saves and notifications for updates (if needed).
