Wrote a lot of stuff about it... But lost it.

To put it in a nutshell: you can duplicate collectibles with this glitch, in a speed run, you can copy your current save, and use it to teleport back to somewhere later for example. You can carry the current sky etc. If you do it during the first cutscene of the game, where the sky is all black, it will be all black in the slot you loaded.

"a lot" of stuff can be made. In the video, I used a save near the end of the game to do: New game to last room.
