So first of all, amazing work on the atmosphere(I even turned my lights on o.O). However I kind of didn't know if it was actualy possible to get help and I didn't really understand what my commands did. From what I understand the black screen is a game over, but perhaps it could have said something like "conection lost" to give some more feedback.
All in all I would still say this is overall a great experience
PS: Man I think it's really creepy if games know your name XD
