I thought I'd contribute some information and tips for saving time on this game:

• Moving forward (the direction you are facing) is the slowest way to move along the ground. Moving backwards, sideways or diagonal are all slightly faster

• You can change the direction you are facing when the game starts by moving your mouse during the loading screen

• You can also start holding down the sprint button during the loading screen

• Pushing the chair away from you (scroll wheel) makes it easier to clip out of bounds

• Shaking the chair (small movements with the mouse) make it easier to clip out of bounds

• After opening the coffin you can spam click to get the key, the coffin won't close until the opening animation is done

• FOR NO OOB the fastest way to go up the spiral stairs is to look up and do lots of jumps

• FOR NO OOB after completing the electricity box puzzle you have to wait about a second and a half before exiting the puzzle screen. If you exit the puzzle too quickly the lever to open the gate wont work.

• FOR NO OOB after opening the gate if you get the key quickly enough you can exit before the gate shuts again. If the gate starts to shut when you are halfway out do a small jump and it wont push you backwards.
