Atmospherically this was really really awesome - I went in blind, and the initial vibe had me on edge expecting some kind of horror. Was really cool to slowly explore the facility, the music in the break room was like hauntingly beautiful with the setting.
Also the shot at the end! So good!
Nice story setting, enjoyed it - the only trouble I had was when doing the pressurise window I pressed escape to try and close it, which didn't, and then lost my mouse and couldn't click the pressurise button or anything so I had to restart :P
