Not sure if this is unique to me since I'm using Joiplay, but the game crashes as soon as I encounter an enemy. Can't even get past what I assume was the tutorial.

You're not the first, I heard reports from several players that the game has problems running on smartphones and tablets that try to play the game with engines like Joiplay.
I unfortunately have no knowledge in regards of joiplay or any other engines that run rpg games on mobile devices. Maybe it can be done with the right settings? I sadly don't know. If I had to guess from looking at the crash text, Joiplay seem to has trouble handling some of the external plugins which the games uses.
I sadly can only guarantee that the games runs on Windows and Linux, those are the systems that I tested it with myself. Sorry, unfortunately there is nothing I can do about that-_-
