so basically (games) you have to do the whole demo with just One Item and the best item for that is the fire extinguisher im not gonna tell you when and where you have to use it but its needed to beat the whole demo also you don't have to go through the elevator you can leave through the door if you wanna cause thats how i did it. (editors note: it is beatable with no items but you have to get lucky on foxos spawnpoint cause its random and you don't know where hes gonna be in chaos mode and also i was one comic away from beating the whole demo with No Items but foxo decided to double boing and kill me and i also got a secret death screen (Screamer) )
