The game itself is great and it is very VERY challenging if you are going for completion and I would give it 4/5 stars (some inaccuracy on the engine stops it from being perfect). However the hidden level "Land of the livid dead", which was painful to finish, made me surprised as I had done it since the game doesn't register that you completed it and the only thing you may get is an achievement on the PS3 and Xbox versions. Nothing here since they didn't include any achievement. I know that I should just enjoy the game and nothing more but sometimes is nice to have even a single line of text that tells you that you have accomplished a really hard challenge, and this doesn't happen here...
