Loved it during the jam and love the updated version even more. The floatiness is still a bit frustrating but I made it and immediately wanted more.
You should consider not restarting your soundtrack AudioSource on death, that triad becomes more irritating on each death, which could occur quite quickly (and often) on harder levels. There's more to your soundtrack than those three notes.
Maybe more tracks as well ?
Loved it ! (please update it even more :D)
