100% in-game completion rating. A beautiful, excellently designed Metroidvania, with a focus on platforming gameplay and simple but enjoyable and varied puzzle-solving, while still evoking the satisfaction inherent in exploring and discovering the secrets of a well-realised world. Shifting between different animal forms is a creative mechanic for learning new combat and traversal skills and, while the early parts of the game feel a little restrictive, with a little persistence this soon opens up.
