Phalanx/YMMV


 * Adaptation Displacement: It was originally released for the Japan-only Sharp X68000.
 * Goddamned Bats: The enemies that attack the player from behind in the seventh stage. Hope you have the laser, which can attack behind your character...
 * Non Sequitur Scene: The "Advertise Zone". It's an Asteroid Thicket with advertising signs all over the first half of the stage!
 * One-Scene Wonder: The old banjo player who only shows up in the cover and nowhere else. He's arguably more famous than the game itself.
 * Squick: Many of the organic bosses- for example, the Mini Boss of the fourth level is a brain that shoots worms from its head...
