Huh, I didn't download the RPG Maker addon and JoiPlay still loaded the public build perfectly fine on my AYN Thor. Granted I haven't properly tried the game beyond seeing one of the cutscenes in the gallery, so maybe something will break if I continue. Also, I got my download from the JoiPlay website as opposed to the Patreon, so I don't know if that changes anything. https://joiplay.net/
