Hey, I just got around to playing this and I really enjoyed it!
I discovered a pretty bad bug near the beginning though which prevents you from being able to save the game. I managed to replicate the bug a couple of times and it's pretty easy to avoid once you know what you're looking for.
If you go into the control room before getting the backup power online and click on the second computer (the security cam one) you don't get a close up but you can't open the menu any more. It's possible to walk around the place and not be able to open the menu at all. Thankfully, clicking that computer at that point in the game isn't at all necessary so it's easy to avoid once you've pinned down the cause. I'd guess that the game is disabling the menu because it's acting as if you've gone into a closeup on the computer when you haven't.
