Nefarious is an action platformer that looks pretty cool. You play as the villain and kidnap princesses who give you abilities depending on which one who have with you. Not to mention, the boss fights are reversed and you get to play as those big bad mechs and try to squish the pesky heroes.

The art is really stylized and cool too.
Notice they even have a monstergirl princess.
Unfortunately it's not funded yet, but I hope it does get funded because it looks really fun.
