Miku Flick

Miku Flick (ミクフリック) was a 2012 rhythm game created by Sega and Crypton Future Media for the iOS operating system for iPhone, iPad and iPod Touch.

Miku Flick was the first game in the Project Diva series to ever be released outside Japan in English.

On September 29, 2017, the game ended its service and was removed from the App Store, with the official website stating "various circumstances beyond our control" as the reason.

Arrows will automatically appear on the tiles to be flicked so as to make things easier for the player, though this help can be removed via the options.

The Disappearance of Hatsune Miku -DEAD END- is unlocked after clearing every song on easy and normal mode.
