Was shocked when I read this was your first soundtrack because it really sounds professional.
The art is amazing and the shader to make the screen warp is really cool to.
My only suggestions would be to hide the stars when they are behind the asteroids because I feel it detracts from the experience a bit. It would also be really satisfying if the user could unlock little blasters to use on the rebel ships, though I understand that it was probably impossible within the scope of the jam.
Really great job on this one!!
