The difficulty curve is a bit weird. I had like 8 red potions in a row so it was super easy and boring, and then suddenly I have to figure out a bunch of new potions and lost super fast. Tried again, this time it was only like 2 red potions then it changed, but it was easier, and then at some point there was one where I just had to experiment to get it?? One hidden ingredient. Idk, I guess you gotta just sacrifice a run to try to figure it out but that was too much for me :(
Edit: The game is really cute and rather fun for a while though! But it gets a bit frustrating with the sudden cruel difficulty spikes :(
