Can you guys tell me what the door glitch does im so confused I just dont do it in my run

There's alot of glitches you can do with doors, you'll have to be more specific

Door Clip - Allows you to clip through that specific door that you do the glitch on Door hop/boost - Put's you on top of the door allowing for OoB segments Wall Ride - Makes your hitbox shrink allowing you to fit through small gaps or jump out of bounds
