Project SEKAI COLORFUL STAGE! feat. Hatsune Miku (also known as “Project SEKAI“or “Proseka“) is a rhythm game developed as a collaboration between SEGA, Craft Egg, Colorful Palette, and Crypton Future Media for iOS and Android devices.

Players have to tap, slide, flick, and trace to match new free-form rhythm notes. Colorful Palette wanted to create a game everyone could play, regardless of skill.The game features many VOCALOID songs. Players can switch between the original VOCALOID versions and SEKAI versions, sung by the game’s characters.
