For those who have trouble with JoiPlay, I've made an Android (APK) version. It's a first draft, this is the 1st time I've made an Android version by moving the savegames to Documents. And, even though it still works fine as it is, I need to update the permissions for the latest versions of Android, to simplify installation.
Later, I'd like to add a few missing options (Quit button, Rollback side, Dialog box background opacity, Quick Menu customization).
Shadows of Desire v0.4c Tier 2 for Android:
Savegames folder: [Device storage]/Documents/RenPy_Saves/shadows.of.desire
Mods folder: [Device storage]/Documents/RenPy_Saves/shadows.of.desire/game
