Overall/Prologue - One character in the Killing Game is a kid (14). I voted yes because I personally believe that putting a child in a killing game is considered abuse.
Not fully, but BDA's are usually a tiny bit shakey and static. Also when a character gets scared the screen usually mildly shakes. There's also a scene where the MC's vision goes blurry.
I suppose this more meant romantically, which no - but one of the participants of the killing game is 14 years old in comparison to participants in their 20's.
Prologue - One of the characters has a snake tie, but as far as I'm aware the game doesn't actually feature a snake. (If you mean the slang for an untrustworthy person, that could be possible.)
Prologue
- Character opens eyes after going closer. (Close to the start)
- Sudden gunshot sound.
- Not a jumpscare, but they make you think there's gonna be one when it says "You never know what could be hiding behind the corner."
