All purpose "What Was That Movie/Game" threads

[Sacks]

I rented this NES game from Blockbuster once and I've been trying to figure out what it was for years and years now. It was set in what I believe to be a space station, and it was two player co-op top down kind of like Guerilla War. I'm pretty sure first player was a boy in a blue and second player was a girl in red. You basically tooled around this space station shooting these like, swirly blob things until you collected enough things/points/enough time had passed until these huge doors opened at the top of the level and you fought some sort of alien boss. Does anyone know what this is?
