So the berserk / straight rush strat time is much faster but you need good rng to go with it and not running into any of the game's bugs helps, I ran into so much unusual occurrences of the game I lost about 30 minutes outside of mistakes. Sub 6 hours is possible but this category is too boring for me to continue.
If you want to know why this run is the most Cursed run I've ever completed, just take a look at some of the highlights I've listed.
28:10 - 29:24 - Barnabas gets possessed, goes completely off script, gets stuck and takes the longest path. 51:33 - 51:50 - I get grabbed by a poltergeist mid air. 2:05:05 - 2:07:19 - Terrible RNG with gear. 1:50:50 - 1:51:30 - I get strangled by a poltergeist and then learn how to fly D: . 5:38:31 - 5:39:45 - Random NPCs try to assassinate my quest giver. 6:18:20 - 6:19:25 - I encounter an unusual amount of enemies on screen trying to ruin the run.
