- Accidental Innuendo: All of David's lines about looking for "D" result in a lot of accidental Ho Yay due to the Memetic Mutation associated with the letter.David: [Forrest] still helps me out nowadays in my search for 'D'.
- And You Thought It Would Fail: Apparently Microsoft didn't have a lot of faith in the title, giving very little advertising and attention to it despite it being an Xbox One exclusive. When it later got a PC port, however, it got very good sales, awards and a sizable fanbase — enough that it would have led to a second season, had SWERY stayed at Access Games.
- Awesome Music:
- The jazzy main theme which calls TV shows to mind. The full version is even more awesome.
- "Drank Dead DOM Die", which plays during action scenes. It sounds like something from the Dropkick Murphys' repertoire.
- "Arousal", usually Roland Walken's theme but also plays when about to dive into the past. Smooth and hauntingly beautiful.
- Fridge Brilliance: The stamina meter makes a lot more sense when you realize David hardly ever eats, almost everything that goes into him is alcohol and sugar. His bad health has him constantly on the point of collapse.
- Older Than They Think: Not the first adventure game where you play as an agoraphobic widower named David.
- Scrappy Mechanic: The stamina system feels awfully restrictive, which really discourages checking everything out. Thankfully, an update reduced stamina usage and increased the stamina recovery of food items, so it's not as annoying as it used to be.
- Squick: Watching Kaysen eat is equal parts amusing and disgusting.
- Uncanny Valley: Invoked with Roland Walken. He is near-inhumanly tall, often engages in repetitive movements in a stiff fashion, and his speech is very delayed. And he never blinks. Ever.
YMMV / D4
