YOU ARE THE VESSEL. Trapped within the decaying walls of the Penrose Sanatorium, you are no soldier. You are a sacrifice. Hunted by a fanatical cult and a bored, omnipotent Entity, your only goal is to escape a world where the architecture itself is your enemy. FEATURES: THE DIRECTOR AI You are never truly alone. An advanced "Director AI" monitors your stress levels, dynamically pacing the horror. If you get too comfortable, the Sanatorium strikes. If you are on the brink of breaking, it lets you breathe—just long enough to give you false hope. OUTWIT, DON'T OUTFIGHT Combat is a fatal mistake. Use stealth, distraction, and the environment to survive "The Enforcer"—a relentless stalker that evolves its tactics as you play. Learn its patterns in Act I, but beware: by Act II, it learns yours. NON-EUCLIDEAN LEVEL DESIGN The Penrose Spire connects the asylum’s wings in impossible ways. Walk down a corridor and end up where you started. Enter a door and gravity shifts. Solve reality-bending puzzles to break the loop. LIGHT IS LIFE Mechanics that matter. Light regenerates your sanity; darkness decays it. Manage your resources—matches, flares, and batteries—to keep the shadows at bay. TRY BEFORE YOU DIE Play the complete first Act and the "Looping Corridor" puzzle for free. Unlock the full nightmare with a single purchase. ## Key features - Dynamic AI Director adjusts horror pacing - Stealth and environmental puzzle-solving - Non-Euclidean architecture and puzzles - Sanity management with light/darkness mechanics - Evolving enemy AI ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/endless-stairs-scary-game/id6757702634/reviews.md ### 5/5 — love it *2026-04-30* i was waiting for this game from 3 months and now i am playing it love the horror theme. ## Frequently asked questions about Endless Stairs ### What is the gameplay like in Endless Stairs?
