Now this one is actually quite good. It's about a guy who has a rare condition, his sperm instantly impregnates women and kills males, so as the preview shows, expect a lot of male guro and even a sectioned penis.
The boss fights are with huge female opponents that can obliterate and even devour the protagonist. I've started playing this one and I loved the gameplay. It's actually a good action-puzzle game that can be enjoyed even if you don't have those particular fetishes.
