Doesn't work anymore. When you try run app it just say that it has trouble reaching AI Dungeon. When you try in website, it let you change few setting actually, but they have not any impact on game anyway. For example, if you add few changes to xml file, you can actually change ai model to dragon, but when you try use it, game says that "you attempted to use the Dragon AI model wchich may have been renamed / removed, or which may require a current gold or platinum subscription..." and then changes it back to griffin.
It seems like now there are server-side checking or something. Idk or this is just me doing something wrong.
