Amazing visuals and banger soundtrack !
I also dig the way you used the theme with the 10 sec hyperdrive reserve, but holy hell is it ultra hard :O
I managed to reach stage 6 with no hyperdrive left and could not go any further
Still i had a good time, i really like the ship designs they are amazingly detailed and i like the visible gradual damage when you fight them that's a neat touch the parallax effects on the BGs are also cool, and again that soundtrack is incredible
Congrats and well done :)
