This is WAY harder than Corridors, this is Ichor Mode. Changes: 1. Of course, as you can see, darkness. You can't really react to something thing that much, you just need to time your closet presses well. 2. Because of the darkness, you need to tell what he's going to do, as he has replaced the functions of the monsters, even the pink door one, which you cant see until it might be too late. 3. Good luck. Technically Ichor is Ω-1, as that is when he starts appearing.
God this sucked to make, mainly the darkness thing. Scratch would keep making the size unchangable, so i have to NOT mess with the size of the darkness. other than that, uh, have fun?
