The mode is most similar to Ninja Mono as the track is fast, black (at default) and there are many coloured blocks that change dynamically to the song. The main difference is that there is no grid for you to store and add up the blocks you collect. You receive no points for collecting blocks and there is no scoreboard to view your results. You are lead directly to the character selection screen when you finish a song, or lead onto another song automatically if the game is running in a window in the background. The feature was added in beta update 4.4.08.
