Fun and unique game! I love the handcrafted art style and sound design. It looks and feels really polished, actually, which is extra impressive considering how short your time was to make it. I think you made some really smart design choices: a complete game starring a blob is much better than half a game starring a detailed animated hero.
There have (understandably) been a quite a few sound-based games made for this jam, but I found yours particularly effective - maybe even my favorite of the lot! I think your game benefits from not relying too heavily on using headphone stereo to pinpoint a sound's location.
My only critique is your collision detection for death could be a little more generous to the player. A couple of times I died while only sliiightly scraping a wall when turning around a corner.
