After beating the game, I decided to tweak the files to get rid of the murderpede and just focus on the climbdown. Tbh, I think this approach is even more pulse-pounding. With the monster chasing you, you rush through things, fling yourself around without thinking. Without, things are slower and quieter, but the dread is somehow worse, especially on the more difficult maps you unlock. My palms were legit sweaty at many points. I definitely hope you add this as an optional mode (and in VR!).
(I just wish there were more of a reward for beating the advanced/inverted maps. The first couple have one neat bonus and I think a line of extra lore, but it was disappointing beating the later ones and just getting the same ending cutscene as before.)
