Will there be an android version?
Yes. The interface required redesign for renpy update. This also requires manually creating a mobile version, which is not yet complete.
You can emulate the Windows version with JoiPlay for now.
Did joiplay patch the bug that caused renpy games to crash on startup?
I see, and no they did not. I'm sure there will be an update soon, after all they have a Patreon... like Bane.
