Bear with me here, as I only half understand how this glitch works.
In my first ever playthrough of the game, I accidentally did this glitch and got to the end early, not knowing until after I watched a speedrun of the game that it wasn't the real ending (though I had my suspicions, as it made no sense). It happens in the hole after the gas station that leads to the toxic-waste-looking area. If you slowly go down the right side, it won't enter you into the room as normal, and eventually you go through the wall and fall infinitely. This will sometimes just cause you to respawn after a bit, but a few times it has warped me to the credits. I think you have to be falling near the entrance of the bottom of the hole; maybe something to do with the game not knowing what entrance you've arrived at and thus defaulting to the credits, though I'm not much of a coder so that is just speculation. This saves a lot of time and I plan on using it in a run!
So it happened so fast that I didn’t realize it was a glitch, which in hindsight sounds dumb lol. A new theory after testing: the final area is stored underneath that part of the level. At one point I was trying to replicate the glitch and it activated the last bug’s dialogue before warping me back to the checkpoint.
I'm not very good yet but just got a run with it at 3:39! It looks like in between the right side of the hole and the little green sludge pool is the approximate location of the end goal.
