Really cool game, definitely a lot of depth derived from the combination of the different mechanics.
One thing I noticed is that I think the camera zooms out a little too rapidly as the size of the ship increases, which makes it difficult to see the different entities on screen, especially the projectiles (which funnily enough is the opposite of the feedback you gave for my game haha)
Also very slight nitpick: I don't think it make sense to have a parallax effect on the stars - they should just be stationary in the background (unless of course the scale of the ship is comparable to that of a star lol)
Overall very well done :)
