Hero VS Succubus -It’s Over When the Cheat Armor Comes Off-

A god drops a hero into a world of monsters, hands him an armor so overpowered a touch sends enemies flying, and tells him to go kill the Succubus Queen. Take the armor off, though, and he's just a soft, defenseless guy in his underwear again.

The plot is thin but functional: divine summons, sacred mission, one convenient loophole. The Succubus Queen figures out the armor's on/off switch is the hero's only weakness and builds her whole strategy around getting it off him.

Play revolves around that toggle, deciding when to stay godlike and when you're forced into vulnerability while exploring a sandbox world full of monster girls looking to exploit the gap. It's a simple power-fantasy premise with an obvious hook, and the game doesn't pretend to be more than that.
