Incidentally, I found the VR version quite easy. I had played the original when it was new and had quite a difficult time with it. There were times I thought I was never going to get through it. But the VR version I breezed through in a few hours.
Now, you might say that I just remembered the puzzle solutions, to which I will counter that I have received too many traumatic brain injuries in the intervening 25 years for that to be the case.
In the original game, lots of important clues were at the sides of the screen. With VR, you have a perfect mapping of the center of your attention being the center of the screen. I wonder if this, coupled with smooth motion letting you see objects from all perspectives instead of 1-3 angles, makes a noteworthy difference.
