I was using 2.14.0 until the new update broke it. Still works with the new update from the quick testing I did. To reiterate, the pathway for using 2.16.0 in joiplay is Formamorph-Windows> app> dist> index.html
I haven't tried doing anything with the AI yet, haven't tried to make a world or play any worlds yet. But I did download a couple worlds easily enough. However when I deleted the default worlds, a tap and hold was necessary and then I had to restart Joiplay to be able to interact with anything after that. And yes, a restart was necessary after each deleted world
The worlds are still gone, but just a warning for that for anyone else that tries this.
Tried the same world as the previous update, and it seems the game works as intended except for the issue with world deletion. But I still haven't tried making a world to play around with because that takes a few hours to make a halfway decent one.
