Nightmare

Nightmare is the antagonist of XerStudios' indie horror game A Dark Place. It is the opponent in FNF: A Malware's Face, in which it infects Boyfriend's computer and drags him into its broken world. The mod is only a demo in its current state, with the possibility of a full release being uncertain.

Gameplay Mechanics

 * Screen Obfuscation: During "Nightware," static will obscure the screen at times.
 * Screen Lock: During "Nightware," occasionally a lock and chains will appear over the screen, and error screens will appear.  In this state, the player cannot press any notes.  The player must move the mouse over the error screens to dismiss them and remove the lock.
