The Metronomicon: Slay the Dance Floor is a rhythm game developed by American indie studio Puuba. The game was originally released on September 29, 2016, for Microsoft Windows and MacOS, under the name The Metronomicon. On August 29, 2017, Puuba released the enhanced edition under the new, extended title which added new playable characters, passive abilities, Endless Mode, and a cooperative option for all modes of the game. The new version was released for PlayStation 4 and Xbox One on August 30, 2017.
The game combines elements from rhythm and role-playing genres. During battles, the player hit notes to the beat of the soundtrack while switching between their team of four heroes. Heroes cast spells and activate abilities by completing rhythm sequences in lanes that scroll over their heads while electronic and indie rock tracks play. Monsters appear on the right side of the screen while the music plays, with new ones swapping in as others are knocked out. Players must swap between tracks on-the-fly in order to heal, cast elemental damage spells, buffs and debuffs. Successfully hitting notes allows the player to launch attacks or defenses against different enemies throughout the songs and levels.
