[BUG] Opening Cutscene Skip / Menu Activation
I'm not /entirely/ positive part of this isn't intended; however, if you start a new game and then you close out of the game before the opening cutscene starts, then when you reload your save it'll show a 0min 0sec save with the location being the "Shuttle". This will then automatically give you the ability to read the messages and go to level select from the jump. This also completely skips the intro cutscene because when you select the first level it loads you directly into the starting chamber. I also tried it if I closed out of the game during the cutscene itself, and the same behavior occurs. This means if anyone's game crashes during the opening sequence they'll never actually see that part of the game.
You can see this in real time at the beginning of this video: https://youtu.be/-qqisGfZbbM
