v1.1 Update

While I did make minor bug fixes, increase the panning speed of the background, and add a small projectile hit vfx and sound, the MAIN thing with this update, was a Boss Asteroid! Watch out for waves that are multiples of 5.. A big shielded asteroid, that spawns homing asteroids when damaged will need to be cleared before the next wave begins. Keep an eye out for the next big update, which will add a working High Score Feature.
