• Goddamned Bats - Bats respawn every time you re-enter a room, and have to be shot down before you can do much else.
  • Most Annoying Sound: The "Ninininininini" noise those walking eyeball things make.
  • Porting Disaster - The Sega Genesis port.
    • The Philips CDI is even worse.
      • To clarify: Dark Castle was heavily reliant on mouse aiming to achieve it's smooth 360 degree shooting mechanic. So, when the game was ported to the CD-i and Sega Genesis, the result was virtually unplayable as the slow rotational aiming using the gamepad made the game essentially unbeatable. The Angry Video Game Nerd was particularly harsh in this regard, although he didn't mention the computer versions of the game.
