Metamorphic Force/YMMV


 * Suspiciously Similar Songs:
 * The boss theme from Stage 2 and the first half of Stage 6 sounds like the first-person levels music from the first Contra game.
 * Stage 5's boss rush theme has a |Double Dare feel. The Amazoness boss theme is basically a modification of one of the Gradius III boss themes.
 * The final boss' first theme is perhaps much like one of The Simpsons boss themes.
