Horripilant is an incremental dungeon crawl that blends idler, puzzle and autobattler elements into a descent through a forgotten underworld. You play as an old battered knight who wakes in the darkest corners of an abandoned dungeon with no memory of how you arrived. The stench of decay fills the air, the walls seem to whisper your name, and a strange tree catches your eye — barely a sprout, growing in defiance of the dark. A voice demands you hit it. A twig breaks off onto the ground, the first of many. Distorted moans echo from an empty staircase, beckoning you downward.

The downward pull carries across over 1000 floors of dungeon, where you fight horrific foes, mine and collect materials incrementally, and solve cryptic puzzles along the way. Your camp serves as a base to explore and upgrade gear, pushing you deeper with each cycle. Every boon carries its burden. The game asks you to repeat, adapt and survive, encountering bizarre characters and confronting the horrors that populate each new depth. Somewhere in those depths you will meet God and become worthy, or the dungeon will consume you entirely.

This marks the debut release from developer Alexandre Declos, available on PC and Linux. For a first outing, Horripilant stacks its layers with ambition — point-and-click exploration sitting alongside autobattler combat and idle progression, all threaded through a dungeon that insists it needs you as much as you need it.
