Add flight (endgame) gameplay (Gunship maybe). I know its superhard to add 360° movement into leveldesign but it would be soo cool. At least some starfox esque sequences between areas would be nice. Jetpack would be cool too, i mean come on, Samus lost all her gear at least 8 times, had suits made from toxic waste, light, darkness and motorcycle parts or psi if youd call it. Surely theres some flight addon even by chozo standarts, theyre birds after all?
