Smooth controls, I liked that I did not have to push a button to interact with the objects, I just had to run through them. Also, the ghost's relative speed compared to the hunters was good, I had the chance to kite them. As nickbdawg said, it felt really satisfying to scare two or three of them at the same time, then getting the hell out of there.
One thing that was a bit disrupting for me in the beginning was that I wasn't always sure about where a wall ends and it stopped me from time to time, but after a while it was just muscle memory.
