The sacred tapes have been corrupted! Help the Harmony Monks banish the HeretiChords and restore the Sacred Harmony.

Every puzzle is a grid filled with enemies and special tiles. Position your Harmony Monks, press play, and watch them spring into action as the playhead sweeps across the board, pushing and destroying every HeretiChord in a single loop.

Each solved loop brings new instruments into the song, one step closer to restoring the tape. Eight tapes, each with its own musical genre.

A small set of mechanics leads to surprisingly deep puzzles. No timing, no dexterity, no luck: just you, the grid and a plan. Stuck? An extra yellow unit can help you through, and the harder version is always waiting when you want it.
