The game is enjoyable, has a god game play, the missions with potions are entertaining and fun, in my opinion the best part of the game,where you have to pick up the ingredients and trow it in the cauldron using the analog stick what makes it really fun, you also have to heat and mix the potion.

The dueling missions are good too, even though is not a challenge, you release new charms to use in the duels during the game and u can also play a two-player duel using the two controls..

The quidditch mission is a bit lame, to repetitive always just a course delineated by stars and don't matter if go forward the difficulty never increases what does happened in the potions and dueling
You can collect the crests hidden in the castle, finding all you get 14 achievements, a really good help to find your way in the castle is call Nearly Headless Nick to show you the places around the school.

Although the game is to short, and to easy you can finish the game with 6 hours playing
