I managed to beat it without actually needing to noclip, but the preview from above helped plan ahead. The last section is quite tricky and luck based because you have to time entering the room, and you need to use the "time turrets off-and-on time" glitch in order to do so. A map that requires a glitch is not a good way of difficult if you ask me. I rated this up, but I wouldn't play it another time.
