The game was released in 2020, with the English version becoming available in 2021. It is still quite active, consistently putting out new cards and events. The stories are also pretty great. If you love Vocaloid, you will likely love playing some of your favorite songs, and seeing how many different designs and versions of the characters you can interact with.
I've been playing on and off since 2023, and actually lost my original account at some point when I foolishly uninstalled the game without linking my accounts... I'm currently level 54!
