Full disclosure, I did watch the stream of Dan creating the level so I knew about the devious little pow block trick. So that helped me out quite a bit. This is still an incredibly difficult level, even knowing the tricks already. Seeing Patrick attempt these levels knowing he hasn't watched Dan beat the level is really impressive. The run he did on the Ryckoning was so fun to watch. I think Dan's claim that the Klepokalpyse is less puzzle-y is not necessarily true. Its definitely more difficult from a platforming perspective, but I think the puzzle elements here are even more obscured than in the Ryckoning.
Here's a video of my clear.
