Post Nut Calamity is an adult first-person roguelike horror adventure made with Unity by Post Nut Calamity. You play a male protagonist exploring a randomly generated underworld dungeon, where animated 2D CG artwork in a 3D game presents monster girls who tempt you to surrender your essence. The game mixes fantasy, horror, and female domination themes as you loot rooms, face enemies, and choose between running away or holding your position.
Development is ongoing with v0.4.2, released October 24, 2026 for Windows, Linux, and Mac in English, uncensored. The v0.4.2 build follows the v0.3.2 update, which added hints for locked gallery entries, camera sensitivity and invert Y options, shop doorways, and fixes for audio, steam traps, floating lights, weapon swings, enemy timing, and floor clipping; it also rebalanced the ranger class and adjusted spawn rates, grapple behavior, and headcage rarity.

Realistically this game is around a 3 for me, give or take. It can be a 2 at times but I can see this growing to a 5 easily if it makes the right choices. Overall, at the state it's…

Many people are just giving 5 stars because of the art. And it is true the art direction is wonderful, that's where it ends for me, this is clearly a demo, as there is no story, barely any different environments…

I love this guy artwork forever and when he announced that he was making a game as well I was estatic, AND HE DID NOT DISSAPOINT. I recommend this to anyone that loves fighting sexy monsters with crispy pixel art.
