Actually, yeah, it is a Game Over Preg. While you're KO'd, get fucked by Goblins until your sperm meter is filled and she'll give birth to baby Goblins.
It kinda feels rushed and quickly assembled together in a "this will have to do" manner. Its not terrible but cant be compared to previous sidescrollers with ankoku artwork like Unbreaker, and its not even close tbh.
