Difficulty changes:
Final boss health: -15%
Acid Roach:
Health: -18%
Acid pool damage: -16%
All roaches can now drop Repair Kits. This was disabled, for some obscure reason.
Decreased the difficulty of some of the hardest encounters in the Haunted (L03) and Librarian (L04) levels.
Note: For this to take effect, you have to load an autosave or quicksave in the previous level (so end of L02) and then continue to L03, or to just start a new game.

Added new options:
Invert mouselook: You can now invert the up-down mouselook.
Mouselook sensitivity.
Toggle idle camera animation: When you remain still for a while, the camera starts looking around. You can toggle this now.
Field of view slider.
Phonodiary auto-play: You can toggle whether you want phonodiaries to automatically play or not.
Aspect ratio filter added for 21:9 (2.33:1). Set the filter to “All” if you don’t see your resolution listed in the list.
Fixed a dead-end in the Office level (thanks TurnSpender!). See this: http://steamcommunity.com/app/629690/discussions/0/1519260397794465258/.
Fixed: Hardware cursor flickers while mouselooking.
Fixed: Restoring HP and EP is not 100% correct in rare cases.
Squashed a few other nasty bugs. (No roaches were harmed! That’s up to you guys!)
