From Strategyinformer.com: "What was the last game you played where you felt the audio was an inextricable segment of its whole? Where the sonic accompaniment wasn’t just a stylistic flourish or a means to create a mood but a crucial part of the game’s logic? To some degree, sound is an oft-overlooked and perhaps under-explored facet of video game design, playing second fiddle to aesthetics and the mechanics of interaction. Fract OSC subverts expectations by making the aural component of its puzzles the primary mechanic, requiring you to hone in on every shift in pitch and change of melody. It’s a conceit that will doubtless divide opinion".
