Inspired by the likes of Earthworm Jim and Mega Man, Nefarious sticks with platformer tropes, with one inversion: you are kidnapping princesses. And each princess you kidnap changes how your character controls and plays. A princess with wings will make you lighter, for some reason.
I don't know why there are so many princesses in a world full of militarized police drones, cars, and bombs, but the animations are nice.
You also get to foil heroes, not just nondescript police. You get to be the jerk in the giant robot instead of the annoying gnat.
