Remember all the fun you had with the Great Sperm Race game a while back? Well, now you can step it up a level with Sperm Rider. In this game you play a delighted little guy in a cowboy hat, riding on a giant spermatozoa through a city drawn crudely in crayons. Using your "seed of destruction", set about squishing the local populace, and fend off attacks from tanks, helicopters and jet planes by deflecting their missiles with your long tail. It's all set to brilliant music and has very little to do with any kind of science, but I like it anyway. Just make sure you don't "ruin everything" by dying.
