Hatsune Miku: Project Diva Extend is a music game starring virtual idol Hatsune Miku. It plays similar to most music games. When a shape lines up with its corresponding shape-outline, press the button on the PSP that matches the shape.

The game also includes an edit mode which not only allows you to remake the game's 42 different tracks—including their background music videos—but also allows you to make custom levels using any MP3s on your PSP's memory stick.

To show this feature off we at Kotaku East have made a level out of "Call Me Maybe" as sung by Hatsune Miku herself (created in Vocaloid by YouTube user Alpha41137).

To see it and the rest of the game in action, check out the video above.

Hatsune Miku: Project Diva Extend was released for the PSP in Japan on November 10, 2011. Stay tuned to Kotaku East for the full import preview later today.
