While playing this game casually I found that if you die (while in cat form?) you enter a state where pausing dose not fully pause you while in cat form, allowing you to hover at a specific height among other things.

That is a video where I trigger the glitch, and show/talk about some things you can do with it. With it you can... ... hover over invisible walls ... climb steep hills ... avoid trigger zones (enter the snow area early)

and probably more things that I don't remember/know about.
