As always, you've NAILED the atmosphere. You're really a master of sound design in my opinion and this game is no exception. The setting and noises had me paranoid most of the time. I also really enjoy the FPS mechanics! Usually these games have little interactivity so it's really cool to have a legitimate game mechanic to play around with. It made that final sequence quite fun in my opinion!
(Spoiler if you haven't played) I don't like the very end. I understand that it's meant to be fun, but it's just goofy and doesn't fit the game at all. Really took me out of the experience. It's not a huge complaint, just a small nitpick.
I had a great time playing this and I'm looking forward to more, thanks for making it!
