A hardcore percussion rhythm game that simulates the feel of a drum kit, differentiating between bass drum, snare drum, and cymbal multi-track notes. It primarily features rock, metal, and jazz tracks. A precise judgment system supports tiered scoring (perfect, excellent, and flawed), and a built-in custom speed adjustment function allows for slowing down difficult tracks for practice. It includes an online leaderboard, supports local screen recording to save perfect playthroughs, contains 40 original rock tracks, can be played offline, and is optimized for tablet screens. A dedicated percussion practice tool for rhythm enthusiasts.
