It's a bit unclear what's demoing visuals vs. gameplay. It seemed often that when the player reaches a corner, instead of turning the corner and continuing down the corridor the player would sometimes turn into the corner and wiggle. I wonder is there something about corners that's a bit janky or is that just a habit of this particular user that they sometimes just turn left and right randomly particularly in corners?
