Destroying the giant moon with your mouse controlled laser never gets old. It's easy to do, it's fun AND it's encouraged! Most games would require you to patiently dig into the moon - not so here. When you eventually grow tried of spelunking, hit the "escape upwards" spacebar for a treat. My new goal in life is to burrow into my backyard as deeply as possible, then hit spacebar. I had no idea that Python and Pygame (which are not hardware accelerated) could be used to create a game like this.
