The player uses the HTC Vive's handheld motion sensing controls to operate two shields, colored blue and orange. The player uses these shields to block incoming orbs of the corresponding color. Sometimes the player must block purple orbs by holding both of the shields together.
The level generation is done in a similar was to Fitterer's previous Audiosurf series. The user supplies the song, and the game generates a series of orbs to match the beat of the song. Songs can be stored locally, or run through YouTube Streaming.
