I had to play it a couple times, but I eventually got the concept. If you're very deliberate with which notes you absorb and when, you can actually make a pretty peaceful melody (barring the mic problems). I think the biggest thing that could be done to improve this game is to program a lot of control over when the sounds come in/out. Instead of repeating to the exact moment the player 'got' the sound, round that out onto a fixed timescale (you could even let the player adjust this manually for faster rythyms) that actually guarantees a consistent zen melody. That way, the players can still control when sounds come in, but it will naturally integrate into an actual thing, with plenty of variation still. The current build is kindof guaranteed to just create an admittedly unpleasant cacophony of noise for new players, but I think this change could improve it tenfold
Also, side note, breathing into a mic never works to achieve that 'wind' effect you were going for. often times sounds like that are replicated through other means. look up "ways to replicate x sound", and you'll find a lot of clever practical solutions to this problem. something as simple as dragging one piece of paper over a certain surface may create the sound you're looking for. (not to mention the added flair that organic sound would provide a project that is trying to be zen, after all)
