At first I just threw anything I could grab into the cauldron because I was picking up every single thing. When I started paying attention to the recipes the game did well and was coming together nicely. I was concerned there wouldn't be enough time to get the right ingredients as you can interact with almost everything in the room but I'm glad you added a feature that resets it whenever you get a correct ingredient because the curses definitely are enough to impact the difficulty! Good job!
P.S. You say you used pre existing art but I could swear I saw progress updates of someone making the witch on the discord channel? Was it everything else in the room that's pre-existing then?
