• Crowning Music of Awesome: Both the US soundtrack and the Japanese soundtracks. Such as "Dark Clouds" from the Japanese soundtrack.
    • However, the US soundtrack is divisive - while some love it for the techno, many veterans despise it to the core.
  • Demonic Spiders: The laser-shooting ships in stages 3 (who reappear again in later levels). Your shield is unable to block their devastating lasers, which will more often than not cost you a life or two.
  • That One Boss: The miniboss of stage 3 takes a very long time to die without the laser. And the final boss also counts, it starts flooding the screen with lots of Hyper Destructive Bouncing Balls, making it a pain to avoid.
