I'm just used to instant turns, is all.
Looking back at it, wow, half of the time I spend on the entire run is in Access. It's becoming my most feared floor now, usurping Research.
There are a number of severe problems in doing a pacifist run:
Matter is probably the biggest. There is very little matter to be found lying around without destroying robots for it. This limits part swapping, firing to open walls, etc.
Then there's the difficulty in getting sensors/interpreters without being able to kill watchers. I ended up not using them at all. I did find an Imp. Sensor in factory at one point but I didn't even notice.
The first few floors are quite a different experience when you can't kill anything. Fortunately, restarting that early on is no big deal, but I did manage to get through it at a high success rate before I completely lost my patience and started playing as quickly as I was in the video.
Lastly there's the fact that by the time you reach Access, you probably have a dreadful build going. Access is certainly the toughest floor of the game and despite being quite experienced at finding the exit, I was unable to do so several times. It's like a ticking time bomb because such a squishy build is not going to last very long at all. Hacking the location of the Access exit is a huge deal, but whether or not you have the right hacking gear and whether you luck out with the hack is another matter entirely.
Also it seems I did use an ECM suite towards the end of Access, but it didn't have a real impact.
