Tired of short games at full price. Great game to rent, but don't waste your money buying it.
The graphics for the game are comparable to better quality PlayStation 2 and Xbox games, but with nice shaders in place so you get the shine on rocks and other wall textures. Still, I have a feeling that they focused too much on making this a cross platform game, and this ended up hurting the graphics quality on the 360 as the models are not super hi-poly, and there's not extensive use of normal maps.
The puzzles are all simple, and while you have to re-play sections a few times before solving them, they are all fairly obvious. Which is great, until you realize 7 or 8 hours in that the game is about to end.
The game is fun and all, but is definitely a rental because of it's length.
