And so SpermRider was born. Many people, for some reason, thought this animation didn't have a plot. I blame lack of imagination. So I'll go ahead and explain it, even though I don't really see why an explanation is necessary: The western standoff scenes all appear to be just a daydream thought up by some guy in a park, resting on a rock. But that is no rock! He really does have a giant sperm! SpermRider was real all along! And so he goes and squishes everyone.
This city squishing rampage was cut down to just one loop because I was really lazy back then. However in 2009 when I got the opportunity to first design a flash game, I chose to include all the cut content and expand upon this squishy rampage. The result was
SpermRider: Seed of Destruction, which you should go play if you haven't already, as the events of the game take place immediately after this animation.
