- It's Short, So It Sucks!: The main criticism leveled at the game is that it's too short, capable of being beaten in 1-3 hours depending on your puzzle-solving skills and whether you look for all the hidden pages or not. In response, the developer announced that the game would be receiving multiple additional levels as free DLC later in 2019.
- Nightmare Fuel: As you'd expect from a game set in a series of inescapable nightmares, DARQ has tons of it.
- At the end of the Cogs stage, the lampshade head creatures you snuck past earlier come screaming up the (vertical) passage you'd just closed and begin banging on it.
- If you turn the light on in the storeroom at the Theatre without finding and putting on the puppet mask, all the puppets suddenly revealed by the light come to life and pounce on you at once.
- The terrifying sequence in the Train dream where you have to solve a simple rotating maze puzzle while the camera rotates around to show you the monster slowly coming down the hallway towards you from beyond the fourth wall, getting closer and closer with every rotation, while also making it hard to see the puzzle.
- After an entire game of slow-paced, atmospheric, stealth-based puzzle solving, the Caves level's frantic action-packed Escape Sequence will surely get your pulse racing.
- Overshadowed by Controversy: The whole thing with Epic Games refusing to sell DARQ unless they could do so exclusively made Wlad Marhulets a hero to PC gamers for refusing to break his promise to give the game a Steam release, but it came to heavily overshadow most other discussion about the game itself.
YMMV / DARQ
