* CrowningMusicOfAwesome: Both the US soundtrack and the Japanese soundtracks. Such as "[[http://www.youtube.com/watch?v=OdUWftOzxBw Dark Clouds]]" from the Japanese soundtrack.
** However, the US soundtrack is a LoveItOrHateIt- while some love it for the techno, ''many'' veterans despise it to the core.
* DemonicSpiders: The [[http://www.users.globalnet.co.uk/~bevhome/biometalstage3-1.gif 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.
* LoveItOrHateIt: The US version's soundtrack is either a cool, heart-pumping techno, or a piece of garbage compared to the Japanese version. No exceptions.
** Many people who hate it state that the US soundtrack is a complete SoundtrackDissonance, given the dark nature of the game and graphics.
* ThatOneBoss: 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 Ball}}s, making it a pain to avoid.
