A few things that could make this better is a tutorial, be it a list of things that you can do. i.e. travel to the left to get potion ingredients.
A bug I ran into is that if there are two orders of the same potion that both restrict separate recipes, then it doesn't allow you to brew the potion at all.
Background art looks really nice tho. Props for the art style. Unfortunate that the gameplay to hinders the potential of the nicely decorated stuff.
