Did this with a crewmate who was playing this on Xbox one too. Some of the glitches include black screen in forest to get up to lookout point faster, land on roof of church while sword blocking to reduce damage (I think they failed at that) and lastly go up clock tower and run along the left passage roofs (the one that has the churches memoir is on this side aswell) then you jump over the gate and run to the house as a head start not sure if my other run went through. I had to screen record through Xbox app btw, Enjoy!!! First time ever speedrunning btw
