So I played asteroids and I would say the ship really moves to fast and slows down too fast as well, I would make it a lot slower - both. As well as shooting because for now standing in place shooting and rotating seems to be the most optimal way to play :)
Other than that really works good, music is a bit loud (I tend to make all of my music and SFX at -15 from the very beginning) but it's nice fitting
Nice job!
