This is a fun game in an immersive setting that is easy to visualize. The layout of the town outside the castle was believable and not too overwhelming, and there were some really interesting locations that were fun to explore. I chuckled a few times at some of the descriptions (the runaway cart, and the potatoes, for example).
As with your other games, the puzzles are unique and engaging, and add to the story (I liked washing the sewage off). Some of the puzzles were not as obvious as they should have been (SPOILER: like when you have to search the grass to find the hook), and a hint system would have been helpful for figuring out what to do when stuck (I kept thinking I needed to get the crowd to move by throwing a potato at them or something).
I loved the introduction / backstory, but I wished there was a bit more added to the storyline during the actual quest. Tell me more about the cake! Your uncle was a farrier, but did the king invest in his small business? I liked having the random interactions from the old man, little girl, etc., but it would have been fun to have some interactions that had to do with the backstory (e.g. if the old man asked whether you had an invitation to the ball and was hoping the king could taste your cake).
Overall, the game is a good length for holding my interest, and the setting and puzzles are enjoyable. I'd love to see the story fleshed out a bit more!
