The idea of switching frequencies to reveal Platforms was an amazingly elegant mechanic! Just with those three blocks you managed to come up with a bunch of cool puzzles. Graphics were perfect for the game type, the tone noise was okay, I agree with +7 though, it did get a little annoying, but I'm a huge sonification fan, so having to use ears to find solutions was up my alley. Perhaps when switching frequencies a little quicker, or, some visual indication of where you're going, or heading to, rather than just the white noise could be easy, yet effective additions. The opening was also very cool. Big fan, would love to see this expanded
