What's the point of update then?
V3 > V4 fixes:
- Quicksaving function (F5) / fully reworked save system (should be much more stable)
- Doors are no longer closes up behind the player, all interactive objects are saved - you can return back and find any objects you've missed
- Added Difficulty setting (the hardest one unlocks after beating the game for the first time)
- Fixed bug on sex scenes, if player was "captured" while Crouched/Crawling
- Fixed bug with mouth-texture visible, after "forcing out" of 1-st person mode
- Fixed bug with puzzles not combining into 1 book
- "Pee girl" desk puzzles can be reset with "R" button, also fixed problem where this puzzle is "solved", but not "triggering" as solved
