I feel a bit worried about the things you want to add. It would be better if you focused on the main game experience and polished that. The mode that is like FNAF for example is messy with mechanics that feel more like busywork than anything fun. Not to mention the Stress mechanic not exactly being anything interesting as well with how it is now.
It needs to be tweaked and properly explained. And having all girls on the loose on the first night is a bad choice as well. Like with FNAF introducing them one by one and giving them time to shine would help to add personality to them. The game is superficial right now and if you start to overdesign things even more now, then I worry for the future.
