Graphically, this is a very impressive game.
The atmosphere and suspense build up is very good and combine to create a genuinely unnerving experience.
You have some interesting concepts going on, like the number touch pad and I thought the voice acting was awesome and it really gave the tension an extra edge in it's robotic, sterile delivery.
Aside from some small optimization issues and lack of direction at the very start this is a good and intriguing game with some unique and well constructed gameplay. Nice work!
