Synesthetic

"Synesthetic is a game any music lover should pick up. When I played my first round, all I could do was smile. It looks good, it feels good. It’s a trip. This game won’t be leaving my iPad anytime soon." Gamezebo.com (4.5/5 stars)

"...it’s an experience as beautiful and transcendental as it is strange and wonderfully horrifying due to the impressive neon techno visuals." 148Apps.com (4/5 stars)

"A fusion of Audiosurf and Boost, Synesthetic takes you on a trippy ride through your own music while basing its game around the simplicity of tilting." AppSpy.com (4/5 stars)
