A little off-topic. At the beginning of this year, during a discussion about a Chinese map, the following thought arose:

It's a fresh take; in the metatest, you could complete 2/3 of the map only to find out that it's impossible to complete because of an unkillable enemy hero on level 111. But I don't approve of such sadistic behavior from mapmakers, as it's a bit frustrating. When I imagine not knowing about a completely obscure encounter in the ramp and realizing its impossibility after a couple of months of real time, I get goosebumps and have strong associations with the movie Saw; the final soundtrack from it fits perfectly with such a situation.

Despite the fact that this is not true in the current version of the map, the map author (according to RoseKavalier) did indeed intend for this to be a possibility.
As a result, the idea arose: this could be a good plot for a popular video about Heroes. A couple of months to think about the idea, a couple of months to master the technical part (and complete a series of streams about another game), a couple of months of work, and here is the result:
