Crypt of the NecroDancer is a roguelike rhythm video game developed and published by Canadian independent game studio Brace Yourself Games. The game takes fundamental elements of a roguelike dungeon exploration game, and adds a beat-matching rhythm game set to an original soundtrack written by Danny Baranowsky. The player's actions are most effective when moving the character set to the beat of the current song and are impaired when they miss a beat, so it is necessary to learn the rhythmic patterns that the various creatures follow. The mixed-genre game includes the ability to import custom music, and the option to use a dance pad instead of traditional controllers or the keyboard.
