Instead of operating as a "game" where players gain points (by killing enemies) and lose lives (by falling into bottomless pits), this piece of software operates as a music creation tool with editable rhythms that can enjoyed by fans of 8-bit chiptune music.
The point of this music creation tool seems to be either to encourage music upon gamers to help them enter the music world or simply to mix some neat songs for gamers. Japanese game designers, at least, take some initiative by trying to introduce music to a broader audience. This broader audience tends to exclude people who want to learn to play classical piano and people who are already established professionals in the music industry. Aspiring musicians can try to get motivated by this game; it seems rather simple and dull but anyone can make something that has a decent sound to it. This game is not recommended for tone deaf people. All the music from the world can be played; even music from the five major regions of Japan. For example, Scotland's song is Cadence to Arms, the famous song that pretty much everybody has heard on the bagpipes at least once in their life. Other songs are famous such as Kanon which is Pachelbel's Canon. The rest are just simple beats such as found in various forms of rock music in addition to the blues. Sequences can be recorded and played back.
