Recca/YMMV


 * Crowning Music of Awesome: Rave music. On the NES. Period.
 * Game-Breaker: The S-type option, which targets enemies. It's possible in several segments to rely solely on S options to do your bidding, earning points for not firing the main weapon and using your main weapon strictly for Smart Bombs. In fact, it's so broken that in Score Attack and Time Attack, the game refuses to drop an S powerup.
 * Goddamned Bats: Some of the enemies in normal and hard modes explode into aimed suicide bullets. In the special mode Zanki Attack, ALL enemies explode into no less than four randomly aimed suicide bullets when destroyed.
 * Sequel Displacement: For a very weird case of this, see The Unfought entry.
 * So Cool Its Awesome
 * That One Boss: More like "Those few bosses".
