J.M.Rhythm is a black-and-white style rhythm game set in the southern regions of Yangtze River of China. It combines the elegance of Chinese ink painting with the beauty of music. We wish you could feel the depth of traditional Chinese art and enjoy the picturesque scenes of "Jiangnan" while playing this game. It is the first work produced by J.M.Arcady, an indie game team formed by undergraduates. We are dedicated to spreading the essence of Chinese culture through games. One of the game's special features is that you can use our “rhythm generator” to upload your own music and it will generate a corresponding beatmap automatically. The beatmap is written in the form of JSON and allows manual modifications.
