Wow this game runs like shit on my awful laptop. I'll test it more when I can play on a real computer and then give you some actual criticism.
But anyway, I really like the aesthetic; everything is shiny but it doesn't look bad. The little crawling drone thing scared the shit out of me and it's little walk noises are terrifying. The music is the only part of the sound that I wish wasn't there. When I turned it off it just felt better; maybe that's personal preference. As paulojlopes says, it does feel very linear in a RE way unlike System Shock/Deus Ex, which I assume to be your inspiration.
Great work though, I hope to make something this smooth and polished one day!
