Love the aesthetics but I wish there was more feedback on actions. It's hard to tell when I've added things to the bowl, and the only way to tell if I've completed the potion properly is by returning to the shop front and offering it.
Also, not sure why the workshop screen is as wide as it is; I had a devil of a time realizing I had to scroll to the right to find the mixing bowl. It's also weird that some potions require a lot more ingredients than others - like, a lot. I'm a bit daunted by the fact that some ask for 5 or 6 Powder and there's no way to keep track of how much you've added except in your head (and it's not clear whether the Powder has successfully been added to the mix in the first place!)
