Played through your game on stream. I've attached the playthrough below if you want to go through it (vod timestamped to your game).
Overall nicely built and the voices for the customers are great. All the ingredients / potion making feel samey currently (which is fair enough for a jam game but if you want to expand on the game you'll likely have to make them feel distinct from each other somehow). Addition of the king as a final challenge was nice.
