Massacre Instrumental (Remix) - Mistful Crimson Morning

Original song made by iamdadogeofdafuture

Friday Night Funkin' (FNF) is a rhythm game in which the player controls a character called Boyfriend, who must defeat a series of opponents in order to continue dating his significant other, Girlfriend. The player must pass multiple levels, referred to as "weeks" in-game, containing three songs each. Each week, the player faces a different opponent, though some deviate in structure from this via the inclusion of multiple opponents. During gameplay, the opponent will sing a pattern of notes (represented as arrows) which the player must then mirror by using the arrow keys or the W, A, S, and D keys. Some songs introduce more complicated patterns, with the player's pattern sometimes varying from the opponent's or both singers engaging in a duet.

For each week, the player has the option to select one of three difficulties: Easy, Normal, or Hard. As the difficulty increases, the speed of incoming arrows increases, and the patterns of arrows become more complex. The player's high score for each week on each difficulty is tracked and shown in the top corner of the week selection screen. The game contains two different modes of play: a story campaign in which songs are played linearly and a "free play" mode which allows for free selection of any of the game's music tracks.

Mistful Crimson Morning (MCM) is a mod created by Crumby and Currently directed by StoneSteves, formerly directed by LtSazo And Havoc. The main story is based off of the lost episode Creepypasta Squidward’s Suicide (A.K.A Red Mist), although it also features several other official and unofficial versions of SpongeBob characters, be it parody or creepy, as freeplay extras.

A DLC expansion for the mod was originally announced in a tweet, but it ended up being canned due to controversies and burnout, causing it to become its own stand-alone mod: Nightmare Squidward Madness.
