Really nice game! It reminded me of metal gear solid both in atmosphere and music. My biggest criticism though is the camera system. If you are gonna give us a third person camera, which i prefer for a stealth game over the previous version that uses a fixed camera, it would be better to have free camera control to see your surroundings better, because more than once i got spotted without knowing where the enemy was.
Also, the game seems to freeze when i lose, not sure if that's intentional or a bug.
Overall, good work.
