Oh God, that was so intense. The first half is pretty easy, the only thing that matters is whether you get shotgun or not. But when you get to the lost souls room, that's where the randomness kicks in. Only hope and numerous attempts can enable you to do the void glide, otherwise it's just death. Anyway, by implementing better movement I managed to save ten whole seconds compared with former WR. My run is obviously not perfect, but I really don't think that anyone will beat this soon.
