Just wondering if there is an easier way

idk the chances but it is just random for a blue hallway

For ILs just begin the game over and over until you get one

Well, they can't appear in the starts of runs where the intro cutscene plays or in special starts (first new content door, first new new content door, startup after 6th collectible)

@Armageddon15 watch my run lmao

in your run, you start and then reset immediately so that you get a short hallway. i was talking about when you hit begin a new game.
