Does anyone remember this game?

I just remembered playing an online game back in the mid 90s. it was a top down style game where you played as a spaceship that would have to clear each level, then go on to fight the boss. there were several bosses and one main boss, if i remember correctly. also, i remember that all the spaceships seemed to be made out of construction paper. i know this is vague but its all i can remember right now. if anyone can help me find it i would be very appreciative.
