GameZebo: In its few short years on the gaming scene, just about every genre you could ever imagine has been tried on the iPhone. The one notable exception however, at least in my mind, has been an iNiS-style rhythm game. Best known for the touch-based DS hit Elite Beat Agents (or if you’re a real game nerd like me, it’s predecessor Osu! Tatakae! Ouendan), the folks at iNiS seemed like a perfect match for the growing smartphone market. And with the release of Demons’ Score, they’ve proved that hunch right… more or less.
