The game keeps crashing with Spark on iOS, what should I do?
AFAIK Spark uses its own Ren'Py distro, which is not what this game uses. I've made extensive changes to the underlying engine and Spark doesn't support that
That means I can't play the game at all.
Correct. iOS is not a supported platform.
Hypothetically, if I could patch it to work on normal Ren'Py, would you be fine with me sharing it?
