This is a really short prototype! The art seems to be a placeholder art, but it gives the right idea. I think to make a game like this work, you really need some character in the king. There is no real motive for me to start messing around with potions and mixing them. It's not even clear what you are looking for. For a future jam, maybe try to join a squad and work together with them? It seems you've got some basics down, now it's just time to keep going!
