Here is a brief overview of the game, via CFK:
As a space travel themed game, Sixtar Gate: STARTRAIL features music-based storytelling, and cute and lovely artworks that give players more than the rhythm gameplay.
In the game, the player becomes the captain of a science vessel and explores the vast Sixtar System with Shii, the adorable and naive navigation partner. The pair will visit colonized planets and discover various stories hidden behind them through music and Shii’s own story.
Sixtar Gate: STARTRAIL‘s main producer is Lyrebird Ferdinant, the developer of various rhythm games including Pump It Up and OverRapid. The sound director is Sound Souler, also a composer who has featured dreamlike songs using strings and piano in diverse and countless music games.
