Query: Good but hard!

This is one of the hardest games I have ever played! Even for a Harry Potter game (which are usually fairly easy). The dementors don't do much though. What I really hate is that Harry has to go into the basement to get rat tonic for Ron's rat. Why can't Ron just get it himself? The game is really cool, though I wish you could hit Snape with that expelliarmus spell like Harry did in the movie.
