I can really only echo what the other commenters have already said. Graphically everything is solid, and the SFX adds to the atmosphere. The implementation of the theme is excellent and really interesting. But I think it goes almost without saying at this point that a blind player is missing a substantial amount of information to really get anywhere without it being frustrating.
Finding the right processors is an absolute ballache, they need to be labelled on the map or physicaly - or the location given needs to be a grid reference.
It's a very ambitious entry with some really style to it and a creative approach, but it is quite frustrating as a player when you more or less have to resort to trial and error.
