I cant get through the door between the first balcony and the others after I clipped through the gate in chapter 10 after the photo-mode glitch I also cant restart the checkpoint when I'm in the area. does anyone have some tips? or is their something I might be doing wrong?

nevermind i just got through

The clip is annoying, just need to practice to get better at it.

The checkpoint thing happens because we're skipping so much that the game doesn't know where to restart you to. If you die on the balconies the only thing you can do if you want to continue the run is to save and load. Most people just reset if they die there.
