I'll admit it, I've been having a hard time getting to the mentioned boss haha
The way you die when you touch the end of the screen makes this complicated, and it doesn't help that when the scrolling stops (after some asteroids), my ship persists to move upwards, and causes a restart.
Am I missing something, perhaps?
Digging the asteroid sprites and the music a lot, though!!
Not to mention the sheer creativity behind the main game mechanic! Has insane potential.
