is the arson ending even possible? i keep on dying trying to get gasoline outside the hous
Sorry for the late reply!
You need 3 items to get the arsonist ending, all of which go to the living room. First, get the cloth and put it down. Second, use the gas to soak it. Finally light it up with the matchbox. After that escape like normal (If you die after completing all of this you'll have to do it again as it doesn't save!)
