Tension mounts as you hang off of broken ladders that deteriorate underneath you and dodge creepy extraterrestrial cyborgs that are targeting you. You do get power-ups, though, like a bat that can kill monsters lurking a level above you and a jetpack that vauts you up several levels. Getting a jetpack and swooping up past those freaks feels incredibly good. I'll confess to flipping off the game's enemies each time I flew past them.
Spin Up's retro art style fits it goofy sci-fi set-up and there's also great self-aware snark in the way it brings you into the game, too, a la Sword & Sworcery. It's well worth the dollar you'll spend on it.
