2x night length but you have 2 lives. Animatronics gain 1.1x movement speed boost and become more relentless.
Also fixed bugs like jumpscares not always playing, weird bug with the wallhack superpower and not being able to exit cameras. (Press crouch while selected on a camera to exit). Insanity mode still being worked on so some bugs may occur but I'll fix them as I find out about them.
