Soo about the languages I don't think I'll add more, I'm not even an english speaker but I did the game in english to make it playable for the most people possible, then about the clues system I can try to do it, but I won't promise anything, but if it's for potions there shouldn't be any problems, bc the double potion is only for Aria, the remaining ones are for the MC
Oh and last, for the thief, I have not worked on the game for a long time, but I don't think I added that. Sorry if it's true and I don't remember that.
