I know this was months ago, and you may never see this. But just in case someone else does: this seems playable on Android using JoiPlay plus the Ren'py plugin (available in the Play Store). Haven't played all the way through (just started, really), so there could be an incompatibility I just haven't encountered.
But the most common failure modes I've encountered with Ren'py games on JoiPlay don't seem to be a problem: the game starts, the menus are navigable, and text entry doesn't break it.
Just something to chew on if you really wanna try this game.
