I haven't tried with a controller yet, I'm still wicked early in the game because I started to feel overwhelmed and a little obsessive. Need to make sure I can jump back into it at a time where I won't forget to eat or drink!

I tried it a few weeks ago. Streamed it from my PC to the living room, cause I didn't feel like getting off the couch.

It was better than I thought it'd be, but I'm not keen on doing it again, when I have KBM available. Tough to to say how much of the discomfort is just fighting my KBM muscle memory, and how much is "game fundamentally too complicated for controller". I only had one REAL complaint about the way a particular button/input was mapped.
