Chris Buffa (Modojo): Square Enix continues to bring new types of games to both iOS and Android, including Demons' Score, a musical combat game where a woman named Serenity flies through Salem State Hospital & Asylum blasting and slashing a variety of monsters. What makes this title interesting is the soundtrack, with music composed by Kohei Tanaka (Sakura Wars series) and Yoko Shimomura (Kingdom Hearts series), among other artists.
Get ready for off-the-hook break beat action. Surrender to the rhythm and tap like hell. Brave furious battles that combine stunning graphics and amazing background music! This Tegra-based version delivers amazing high-end graphics!

Square Enix Announces Final Fantasy IV and Holiday Mobile Sale
Haven't played too many games on my Bionic but I may have to 'borrow' my wife's iPad.
Only square seems to announce way more games than they actually release.

"Demons' Score doesn’t waste any time reminding you that you’ve only bought part of it. It’s a completely aggravating experience in general, but for a rhythm game? That’s just downright repulsive. It’s sad that Square Enix and iNiS decided to go this route, as the game would’ve been much better off at a slightly higher price with all the content available after a single purchase."
