I really enjoyed the sound track and visual aesthetics. A few hours in however, and I started to feel like a rat in a maze. For a game that is so seemingly geared around movement and exploration - the levels are really quite linear and full of scripted 'puzzles' that have a single pre-designed solution.
In the end, playing for the story was the best outcome I could get. Interesting or re-playable gameplay mechanics are not to be found, unfortunately.
