I'm one of the devs of Radio Flare. I just wanted to quickly announce that we're having a SALE right now. You can get Radio Flare for $0.99 in the App Store. The sale will last until we ship our update. We plan to do that next week. The update will bring some fabulous new features to Radio Flare like online Leaderboards, a new game mode, a tutorial, and ... "more elements that react to the beat of the music". Also, we have Radio Flare on show here at the Game Developers Conference in the Expo hall. We were nominated for the Independent Games Festival Mobile "Audio Achievement" award. Drop by if you're at the GDC.
