Describing the walkthrough is pointless; it will be tedious and unclear. It's much better to watch it in the replays.
As key features of the walkthrough, I would highlight the unexpected "hole" (66,12 - 65,13 subt.), and the battles for the Castle of Death and against the Purple main army. I would also note the difficult logistics on the 5th day in the triangle of Southern Swamps - Northern Swamps - Yellow Portal (115,51), and the "firefighting" level progression with a Haven hero from the Sanctuary (53,49) to Vardik - garrison (65,40). During this level progression, I had to calculate experience not only for the Haven hero but also for the "runner" hero, who ensured the required movement range.
P.S. I watched the videos, but I still don't understand how it was done:( At least briefly, regarding the movements on the 4th day:)
