About This Game

Pick up your keyboard and play it like a real bass! Take on the role of Ostinata, the leader and bassist of the all-girl band Tutti Nova. Strengthen the bonds among the five band members through your performances (unlocking daily band dialogs) while staying ever ready to fend off bassist jokes. At the same time, grow your fan base (advancing the main story chapters), perform in larger venues, and set your sights on the ultimate goal—not the Budokan… but the Musikverein in Vienna!

Bass Simulation

This game can be played with any keyboard, but for the best immersive experience, hold the keyboard as if you're holding a bass or a guitar. Place the four fingers of your left hand on the number keys 1–4, and your right hand on the comma (,), L, P, and hyphen (-) keys. Press the frets with your left hand, then pluck the strings with your right hand, just like playing a real bass! Ready? You're now the official bassist of Tutti Nova!

Bassist Simulation

Knowing how to play the bass is just the first step to becoming a bassist. As the most unique presence in the band, you also need to learn how to handle all kinds of bassist jokes—whether intentional or not. Perform at shows, deepen the bonds between your bandmates, unlock more daily dialogs, and show everyone that you've truly grown into a real bassist!

Run a Girl Band

Together with four band members, each with their own distinct personality, boost your fan count, earn more money, rent bigger venues, and put on even larger live shows—your goal is the Budokan… wait, no, the Musikverein in Vienna! A quintessential girl band story begins right here!
