Okay, I'm done for now and think I can give a fair review
These are my personal opinions and thoughts that came spontaneously while playing, so while it may sometimes be nitpicking, it's honest feedback from a player's perspective.
I started the game and saw the bedroom, very obviously hand drawn. The color choices for the backgrounds are in general very atmospheric, but I would have prefered the lines to be a little more straight since it is a technical environment. It didn't strike my eye that much later so I guess you did the bedroom first and took more care with that as you made more images.
Other than that, the game was visually stunning!
I noticed that you put each sentence into its own line, even several short ones that come one after another. The text box appeared vast and empty as a result and checking options again to see if anything had changed became somewhat tedious. You are allowed to put several sentences in the same dialogue line, especially if they are the same train of thought.
Because I have a long experience with point&click-adventures, I didn't have much trouble with most hotspots.
I didn't find a gun though (I was sure I searched EVERYTHING, and only clicked the vent of the elevator by accident.
Hiding one correct reaction in a lot of "panic" choices was a nice idea, but it stood out too much. Make the panic choices different from each other to REALLY induce panic and randomize the order, in case you didn't already.
The game being silent is a bummer, you can do so much with sound. There are a lot of free CC sound libaries that you can use. Ambient humming, elevator sound, breathing...
I ultimately stopped playing because I think I found a bugged endless loop:
I found my friend, had my proxy with me and had saved before. Getting the monster's attention lets my proxy hit it,
but then the choices reappear (did this 10 times in a row and nothing changed). Running makes the monster bite me and recoil, do it too often and I die. Trying to get my friend out (however that is going to work, he looks like he is melded) makes the monster attack my proxy, do it too often and the proxy dies with the sequence repeating over and over and over.
The strangeness of the society where this takes place is only hinted at, but was done well.
The proxy is ugly, but I felt some kind of pity for it.
Overall, the game got a lot of emotional reactions from me.
Some doors not being clickable irritated me, as was already said you could make them a different color or at least give the player feedback when he tries to open them.
That's all I can think of now
