Timothy and the Tower of Mu - Lamassu Boss Skip

If you mash jump during the dialogue, then dash into the door, and press up while on the door, you can still go through the door.
Keep in mind if you're underwater after the transition ends, you'll enter a glitched swimming state where your oxygen will deplete and that will kill you eventually
