Great game, really loved it.
The puzzles are great but the best thing is the sound design, it's really nice to hear the peasants praying the king. In terms of points to improve, it is really frustrating that the king is always moving. Maybe it is to increase the difficulty, but I believe it adds a layer of reflexes skills that do not let you think carefully the puzzles. Btw, I love the camera movement.
Overall, I am really impressed. Good job!
