The Stalking Stairs

Each hand in The Stalking Stairs runs on its own ten-point stamina bar, and it starts draining the moment you’re hanging from a ledge with nothing under your feet.

The Grip System Behind Every Climb

Nothing in The Stalking Stairs moves your character directly. Your left hand grabs with one input, your right hand grabs with another, and WASD steers whichever hand is currently open toward the next hold.

Reaching a distant grip means letting go with one hand, swinging on the other, and timing the release so your open hand lands where it needs to before momentum runs out.

Each hand tracks stamina separately, ten points apiece, and holding a ledge with your feet off solid ground burns it down steadily. Carrying too much in your backpack accelerates that drain, turning inventory into a climbing decision as much as a survival one.

Sub-Structure 17 and What’s Rising Below

The climb takes place inside Sub-Structure 17, a decaying vertical complex you’re ascending one handhold at a time.

What makes it urgent rather than leisurely is the Mass — a churning, oozing pursuit that rises from below and never stops closing the gap. It doesn’t announce itself with a chase sequence; it’s simply always a little closer than you’d like.

On Hardmode, the Mass moves faster and the creatures scattered through Sub-Structure 17 grow more dangerous, stripping away much of the margin for error a first run allows.

Chalk, Food, and the Rest of the Backpack

Roughly sixty distinct items exist across The Stalking Stairs, and a handful come up often enough that players build strategies around them:

• Chalk, a trinket that makes one-handed climbing more manageable without a good grip
• Food, which restores stamina in either hand whenever you’re safe enough to use it
• Rebar and flares, used to skip past a tricky section rather than hesitating over a route

Common advice among experienced players is to spend items rather than hoard them, since hesitating in front of a hard section usually costs more stamina than a rebar or flare boost would have.

Checkpoints That Don’t Save the Climb

Named checkpoints like the Interlude Lockdown and the Forlorn Gateway mark real progress through Sub-Structure 17, but they aren’t a safety net the way checkpoints usually are.

A fall mid-climb sends you back to the main menu rather than your last checkpoint, making every run closer to all-or-nothing than most climbing games attempt.

That structure is genuinely divisive — appropriately punishing to players who want a roguelite built around a rising threat, needlessly harsh to those used to games that preserve some mid-run progress.

Common Questions About The Stalking Stairs

1. Can you finish a run on your first attempt? Yes — nothing locks a first-time climber out of reaching the top of Sub-Structure 17, though most early attempts end well before that point.
2. What actually kills a run the fastest? Running both hands’ stamina down while still exposed to the Mass, since there’s no way to recover mid-fall.
3. Is Hardmode just a cosmetic label? No — it speeds up the Mass and toughens the creatures in Sub-Structure 17, and clearing it unlocks a mode that strips out assist systems entirely.

What keeps The Stalking Stairs from feeling like a straightforward climbing exercise is that the Mass never lets a careful player take their time — every pause at the Forlorn Gateway is borrowed, and the climb always remembers something is still coming up behind you.
