Game Breaker: The three cheats that are unlocked after 100% Completion, especially Unlimited Stealth. How broken is it, you may ask? You can beat Level 5 in less than 30 seconds with Unlimited Stealth.
It's Short, so It Sucks: Despite being surprisingly decent for licensed game standards, the main complaint against the game is that it can be completed in little under an hour.
No Problem with Licensed Games: As far as most of the people who have played the game are concerned, the game is pretty good. Sure, it's definitely not winning any "Game of the Year" awards and there are some "questionable" design choices, but for the most part, the game is pleasantly above normal licensed game standards.
