@Happy_danser I did that mainly because I was just focused on right-clicking as much as possible and I noticed that sometimes I moved my mouse around by accident when I did this. I don't believe that it helped in any way but I can't say for sure.
In terms of actual movement, I know that I would look mainly at the ground so that when I moved my view with the mouse it wouldn't perform the whole "stop and rotate" action every time that takes about a second.
Hi Goodigo, as far as I have been able to figure out, there are two different ways to skip cut scenes (on PC at least). The first is by using the ESC key and the second is using the 'Unstack' command. Default keybind for this is right mouse click. Now it doesn't seem very easy to do as most cut scenes appear to have a VERY short time to get the command in before it begind to actually play. This means that normally its just easier to mash one of the commands right before you expect the scene to play. Its almost always easier to mash 'unstack', and especially when you're not inside another doll since there isn't a risk of jumping out. The scene before the final fight is actually rathet short compared to others which can save 15+ seconds each.
