Gameplay
Nightmare Diary plays like a typical fangame. You enter the dream world by sleeping in the bed. Interacting with the bookshelf allows you to save. Your main goal is to explore the dream world and obtain effects. There is plenty of dialogue in the game as well.

Plot
KNF appears to have confined himself to his bedroom to dream. There are bloodstains covering KNF's bedroom and KNF himself, the reason for this being unclear.
