Sega has pulled the newly launched iOS version of Rhythm Thief & The Paris Caper.
Sega UK confirmed in a statement issued to Digital Spy on Friday that it has temporarily pulled the game.
"An unexpected problem has been discovered in the version of Rhythm Thief that was available yesterday on the Apple App Store, so we have removed it temporarily from the store as we work on a fix," the publisher said.
"Our development team is hard at work to update the game and it will be back online very soon. Anyone who has purchased the game already will be able to play it as soon as it is back. We will keep you updated and we thank you in advance for your continued patience."
In CVG's 3DS Rhythm Thief review, we said: "The hallmark of a good rhythm game is one that you can play by ear, and Rhythm Thief gets this.
"Each minigame has a distinctive and appreciable flow and the difficulty levels are pitched perfectly - it's never too hard that you run into a wall, but you'll have to rub the stylus down to a nub to rack up an 'A' grade score on your first try."
