I have feedback. This is a cool idea, but it needed so much more polish, and just more stuff in general. The first thing I noticed is that you can go off the screen infinitely as the little black square. Why wouldn't there be borders? The whole method of collecting ingredients like that is tedious and boring too. You could make it a larger map or maze that you can explore to find the ingredients, so there's a bit more variety. The brewing system doesn't work well. Several times ingredients would get stuck or wouldn't go into the cauldron. The trial and error aspect is annoying. It's like struggling to remember crafting recipes in Minecraft. This game could really use some progression. Make the gold have some sort of purpose other than a number. Add mechanics that allow you to forage quicker, like a magnet. You can spend gold on larger cauldrons that allow you to create more complex recipes. There should just be more to this. Games don't always have to have an end goal, but they should have progression of some kind. This is what I meant by borderline shovelware. This is a great idea, but more needs to be built on it for it to be worth my time. You need two things: more mechanics and more polish.
That being said, one thing that I liked was the art style. It's simple and flat, but honestly really fitting for a game like this.
