Lucas Crandles 'Use Of Suspense In Black Button'

In the short film, Black button by Lucas Crandles, the suspense is used throughout the film Because when the guy first shows up in the room he is greeted by a mysterious figure asking if he would rather $10,000,000 and kill somebody or not kill somebody and get to leave and the suspense comes in when he is left with that decision as the tensions rise
Foreshadowing is used when the main character says “my god” and the questioner says
“Oh, he’s not your god” Flashback is used when the questioner says You’re already dead and it cuts to a flashback of him dying on his way to work in a car crash.
