Where is this reddit post may I ask? Because I can't seem to find it anywhere no matter how hard I search.

There are. If you look in the comments section of the trailer you'll see the creator confirming the cross-examinations to the question of a commenter:

Nice game. The story gives me Mob Psycho 100 or Supernatural vibes. Loved it!

Great game. I initially thought this will be a crude game inspired by flash games like 5 minutes to kill yourself or beat your boss but then I got to the last two endings and I gotta say...it was way more than what I expected! A truly unique experience.
