Idols of Ash is a first-person atmospheric horror climbing game developed by independent studio Leafy Games using the Godot engine. Released on April 2, 2026 via itch.io with a free/pay-what-you-want model, the game has rapidly gone viral for its unique vertical descent gameplay and suffocating atmosphere.
Unlike traditional horror games that rely on lateral exploration or combat, Idols of Ash forces players into a relentless downward descent through a massive, ancient abyss of crumbling stone and drifting ash. Your only tools are a grappling hook, a length of rope, and your nerves. There are no weapons, no safe rooms, and no moments of calm.
Deep in the shadows above you, a colossal, chittering centipede — affectionately dubbed "Jerry" or the "Murderpede" by the community — is hunting you. Every sound you make, every hook you fire, brings it closer. If you stop moving, you die.
The game draws comparisons to Shadow of the Colossus for its monumental architecture, White Knuckle for its movement mechanics, and the Backrooms phenomenon for its liminal horror atmosphere. The community has praised its "immaculate atmosphere," satisfying grapple physics, and intense speedrun potential.
Master these controls to survive the descent. The game supports keyboard, mouse, and gamepad input.
The grappling hook in Idols of Ash has a unique line-of-sight dependency that sets it apart from other games. The hook's physics only function optimally when you are actively looking at the anchor point. If you look away while grappled, the rope's tension destabilizes, and you risk falling.
This forces an agonizing camera-management meta-game: you must constantly snap your view between looking down for landing zones, looking up to track the centipede, and looking at your grapple point to keep the physics stable.
New to the abyss? Follow these steps to survive your first descent and reach the bottom alive.
Your sole objective is to descend to the bottom of the abyss. There is no combat — you cannot fight the centipede. Your only defense is speed and smart traversal. Use your grappling hook and rope to swing, rappel, and free-fall through the massive underground structure.
Hold Left Click to fire the hook at beams, rocks, and outcroppings. Once attached, you'll swing like a pendulum. Release at the optimal angle (roughly 45°) to maximize distance. The key to survival is converting vertical speed into safe lateral arcs.
Holding Ctrl while grappled allows a slow, safe rappel. This eliminates fall damage but is dangerously slow. The centipede will catch you if you rely on it too much. Use Ctrl only for completely blind drops where you can't see what's below.
The centipede emits distinct audio cues — chittering, scraping, clicking — as it closes in. Use your ears to track its proximity instead of turning around. Looking back wastes precious time and can cause you to miss critical grapple points ahead.
Three escalating difficulty tiers push your mechanical mastery to its absolute limits.
The foundational experience. Forgiving grapple points, moderate chokepoint width, and a single centipede at base speed. Ideal for learning the physics engine, practicing pendulum momentum, and completing your first descent.
Drastically increased AI aggression and movement speed. The environment becomes significantly darker, requiring near-instinctive knowledge of grapple point locations. Controlled descents via Ctrl become virtually suicidal — you must free-fall and swing constantly.
The apex mechanical challenge. A completely bespoke, secret map with jagged, confusing terrain. You must collect scattered Embers while hunted by up to 4 centipedes simultaneously. This mode features the infamous Viper's Pit — the deadliest area in the game.
Understanding the underlying physics models is essential for advanced play and speedrunning.
The grappling hook is your sole instrument of salvation. Once tethered, the rope acts as a dynamic pendulum subject to simulated gravitational forces. The length of the rope and the angle of your drop determine the arc of your swing.
Skilled players learn to convert lethal vertical velocity into horizontal momentum using a technique called "kinetic micro-grappling": firing the hook at an opposing wall milliseconds before a fatal impact. The sudden rope tension translates your downward speed into a lateral swing, resetting the fall-damage counter without ever stopping.
The developers fine-tuned rope swinging physics in patch v1.1, specifically addressing momentum transfer issues at extreme depths. This indicates that the engine's physics calculations become increasingly complex the deeper you descend.
Idols of Ash employs three overlapping damage models that punish poor trajectory planning:
| Damage Type | Trigger | Mitigation | Severity |
|---|---|---|---|
| Direct Fall Damage | Impacting a surface at high velocity without deceleration | Grapple before impact; use Ctrl for controlled drops | Fatal / Severe |
| Whiplash Damage | Rope reaches max tension without a pendulum arc to dissipate energy | Always grapple at an angle to ensure a lateral arc, never directly above | Moderate / Severe |
| Aerodynamic Drift | Wind resistance during long falls causes aim wobble | Fire the grapple at closer range; compensate for reticle drift | Indirect (missed grapples) |
| Centipede Bite | The creature enters your proximity hitbox | Maintain downward speed; break line of sight; avoid chokepoints | Severe / Rapid Depletion |
Crucially, whiplash damage is calculated based on the mathematical tangent of the rope at the moment of maximum tension. If the rope snaps taut with zero lateral deflection (a dead stop), you take massive damage. Even a slight angle provides meaningful protection. This is why panic-grappling straight up is so dangerous.
The "Murderpede" is not a scripted cinematic monster. It's a dynamic, real-time pathfinding entity that adapts to your movements.
The centipede uses a dynamic real-time pathfinding algorithm that constantly recalculates the most efficient route to your coordinates. It navigates walls, ceilings, and structural beams — terrain you find impassable.
In patch v1.11, the developers fixed an issue where the monster was acting "too shy." Since that hotfix, the AI's aggression parameters have been dramatically heightened.
In advanced difficulty tiers, the AI appears to have predictive capabilities, positioning itself near chokepoints to intercept your likely trajectory rather than simply following behind you.
The centipede has a segmented, multi-node skeletal rig. Each body segment follows the head node's coordinates with a temporal delay. This means the damage hitbox is not a simple sphere — it's an exceptionally long, dynamic, winding ribbon of lethal geometry.
Even after the head passes a position, the trailing body segments continue to occupy that space for several seconds. You must track not just the head, but mentally project the trailing trajectory of the entire body.
Contact doesn't trigger an instant game over — instead, the creature rapidly drains your health over time, giving you a fractional window to break free by dropping or swinging away.
The centipede's greatest weapon is not its coded damage output — it's psychological oppression. The constant auditory feedback of chittering mandibles and skittering legs induces genuine panic, which causes unforced mechanical errors. The game brilliantly weaponizes arachnophobia and entomophobia.
To play at an advanced level, you must consciously divorce yourself from the atmospheric terror. Train your cognitive processes to view the centipede as a moving collision mesh governed by a mathematical velocity algorithm. Once the fear is stripped away, it becomes a formulaic hazard to be mathematically avoided.
The game's physics-driven, linear descent structure makes it a natural speedrunning masterpiece.
| Category | Runner | Time | Key Strategy |
|---|---|---|---|
| Nightmare WR | BubbleCerberus | 4:09.700 | Hyper-aggressive free-fall, minimal wall contact |
| Normal WR | Sir Soli | 4:15.70 | Memorized blind leaps, zero rappelling |
| Community Best | AccurateGrind | 3:44.33 | Extreme angular momentum exploitation |
The 42-second delta between the top two verified records represents a monumental chasm in routing efficiency. In a run barely exceeding four minutes, every millisecond of wall contact or hesitation is catastrophic.
The absolute pinnacle of mechanical and psychological demand. Here's everything you need to know to conquer it.
The First Kiln completely shatters the established rules:
Your routing must become a complex three-dimensional helix. You cannot simply drop straight down — the swarm will converge and trap you. Instead:
Discovered by community member ApocaDoc, this exploit manipulates the game's respawn telemetry and collision detection to bypass the brutally difficult opening section:
This forces the engine to process your falling collision box alongside the deployed hook state, breaking through standard environmental boundaries. You can completely bypass the first room and sometimes land safely in the second room on specific outcropping rocks.
