I would like to speedrun portal OoB, as i only know a few levels (which may not even be the fastest as i made the routes myself) and glitchless, i was just wondering if anyone knows of any tutorials (or the likes) Thanks!

(im on console (switch) btw)

In some speedruns i have occured with the sliding doors closing and the enemy opening the sliding doors getting to his boxes before i could get there. i know this is not an issue with my speed because most of the time this doesnt happen. Is there any definite fix to this?
