I bought this game as soon as it came out on sale as I loved the movie so much I just wanted to play the game on the DS as well! However after a few hours I was quickly disappointed with The Golden Compass.
In the game you play the main character lara and work your way around the boarding school/house. During the game you collect food to gain 'lives' and strength and golden nuggets for extra points. As your progress through the game you can swap between different animal characters which help with problem solving during the game.
Each level normally consists of getting from A to B while completing a few puzzle, such as finding a key to unlock the door, or sneaking past the guards. After a few levels I have found the game quite repetitive but I have enjoyed the problem solving puzzles in the game.
The graphics are quite good for the game and the main character details are quite details, although the backgrounds are all very similar in different levels.
Although this sounds quite a negative review i think this game is suited to slightly younger players maybe under 15's who will enjoy the problem solving during the game.
