The more you look at the apartment, the worse it gets. (press Space to show/hide the text) Weird details like the dust pan, the fridge or the slippers under the desk.
Also, I've noticed a bug in all games, if you press Windows key on the keyboard, all text runs forward like when you hold Ctrl to skip the text. You find yourself in another chapter before you could stop it, and you have to reload a save to go back.
