Music games are always at their best when they're married to a catchy soundtrack and a unique visual presentation. With this in mind, Taito realized they had the perfect person to tackle their first major iOS rhythm title: Reisuke Ishida. Previously responsible for the trippy, challenging, and delightfully retro Space Invaders Infinity Gene, Ishida seemed like the kind of guy who might have the perfect vision for a rhythm game built from the ground-up for the touch screen. As it turns out, they couldn't have been more right.
