At a pricey $10, Rhythm Thief & the Paris Caper is a "brand-new adventure" that features "the addictive timing-focused gameplay from the 3DS release of Rhythm Thief & The Emperor’s Treasure." It's optimized for iPhone, iPad, and iPod Touch and contains 20 songs, 50 missions, and an assortment of minigames.
Limited-time special missions and daily challenges will also be made available to mobile players.
The iOS version is a port of the original Rhythm Thief, which launched on 3DS in 2012. It includes in-app purchases for expert difficulty levels, which are to be "released regularly."
