There are certain spots (mainly detective and scout) that allow you to sequence break and softlock yourself early in the game, Mainly the fence in the backyard of the house thats on the same side as detectives spawn. There's a platform that you have to pull down and up again later in the game for a puzzle but by jumping over the fence and taking fall damage you effectively get into the front yard and softlock yourself. (I don't have footage nor screenshots of it sadly but its worth mentioning)
