This can be done with every ending in the game, but for the purposes of this guide, we'll use the "Future Prison" ending as it's what I typically use for this.


From there, fast forward through to the very last line in whichever ending you've picked.


Now, you need to manually go back to the main menu while the game itself also tries to force you back to the main menu. Clicking one more time here will pull up the screen with all your endings to show you which one you just got, but the buttons on the dialogue box are still active.


When that screen comes up, you need to click the settings icon (the gear icon), click "Return to Menu", and then click "Return to Main Menu." all in quick succession. Be too slow and the game will just send you back to the menu normally. Below is an image of where the return to menu buttons are, followed by the same but overlayed on top of the endings screen to give you an idea of where you should be clicking.



If done properly, you should see two loading screens appear, though only one will disappear. From here, the entire game is still perfectly active and playable, but since you can't see anything (aside from the occasional screen transition), you're basically forced to restart the game. However, if you can manage to do all of this again but now completely blinded by the loading screen, you can stack them. It's pretty difficult to do until you get a grasp on where everything is, but it's entirely possible. Here's an image of three loading screens stacked together. I've gone all the way up to twelve without the game crashing so, it's probably doable indefinitely.
