No clue either. It's possible ypu forgot to add the introduction sequence. Adding an option to check controls in case a player forgets or skips it accidentally would solve that problem entirely. I have noticed that she can hear you open doors or run regardless of distance and most hiding spots that should work don't due to how her vision works or don't allow you to go around her. Her size is a bit of an issue since you can easily get pinned in a hiding spot with no way around or past her ever being present anywhere. My suggestion is allowing us to use the clothes closets as a hiding spot, but make it a mini game to stay hidden when she's close. Mini game difficulty is ramped up to an 11 on hardmode. Just my suggestion based on similar games that do this without the mini game aspect.
