I dont mind if you count the time it took me to reset the game after it crashed

Note from Moderator: Added 4 seconds to account for the early time stop, approximately around the time you said "stop the timer". Time stops on the Chapter 16 results screen after any "Loading..." screens. Aside from that, well done! You are the first to have an Ultimate Nightmare% run verified on the board. Massive props to you!
