The music is great, and it is fun going through all the levels. My only complaint is that is can be difficult, especially for young or new players. I like some difficulty, so it is great for me.
The begining of this game is great, and I love the summonable creatures. Sadly, once you gain the ability to fly, the world feels very small and becomes far less interesting. You'd think flying would be the best part, but it is rather limiting.
