Please be as specific as possible when letting us know what is missing or incorrect. For example, say "this game's trophy difficulty should be 8/10", with a link to a website corroborating this difficulty estimate (if possible), not "this game's trophy difficulty is wrong".
Nightmares from the Deep: The Cursed Heart Demo does not have any trophies. This is because it is a demo and/or soundtrack, neither of which typically get trophy lists. The full (i.e., paid) version of the game likely has a trophy list.
Nightmares from the Deep: The Cursed Heart is a classic adventure game that tells a gripping tale of undying love. Assume the role of museum curator Sarah Black and take control of your destiny to stop the undead Captain Remington and save your daughter's life. Jam-packed with chilling locations - from rotting shipwrecks to dank and mordant caves. Use your wits to find clues, solve puzzles, and uncoil the ancient mysteries of Skull Island before it's too late!
