Grappling Hook: Physics Escape

The acid is rising. Your grappling hook is a magnet. Climb, or drown.

Grappling Hook: Physics Escape (world name: RUSTIDE) is a single-player physics platformer set in a flooded rust canyon. Every steel beam, oil drum and hanging crate is a real rigid body with mass, friction and momentum - and your magnet grappling hook can grab all of them. Heavier than you? You get yanked to it. Lighter than you? It flies to your hand, hovers on your crosshair, and becomes a weapon.

HOW THE GRAPPLING HOOK WORKS
- PULL (left): hook a girder to slingshot yourself over a collapsed road, or rip it free and hold it.
- PUSH (right): blast the held object away, or shove off the ground for a mid-air second launch and a panic save.
- CHARGE & THROW: hold, release, hurl. Damage = mass x speed, so a heavy beam at full speed punches through a whole row of enemies.
- Beams are load-bearing. Snap the wrong support and everything above chain-collapses - on them, or on you.

OUTRUN THE ACID TIDE
Glowing green acid floods the canyon from below. Under the surface you lose health every second and metal corrodes: soaked beams turn light and brittle. Every energy core you deliver to the central elevator raises the tide one more level, so the route you just learned gets eaten floor by floor. Deliver eight cores, start the elevator, and escape over the top before the acid gets there.

FEATURES
- Real physics, not scripted: objects roll, stack, crush and collapse, so every fight permanently rewrites the map under your feet.
- 99 procedurally generated ruins - higher canyons, weaker structures, faster tides, and a gate-warden machine boss every 4 ruins.
- Build a run: every magnetic core drops a 3-card choice - twin hook, heavier pull, throw crits, slow motion, shield, magnet regen, no fall damage, object damage up.
- Enemies that obey physics too: patrollers, climbers, flyers and shooters can all be swatted, crushed by a thrown beam, or shoved into the acid.
- Endless mode unlocks after your first escape - see how many tide levels you can survive.
- Rust scrap earned by playing permanently unlocks gun modules and deeper starting ruins.
- Handmade touch controls: left thumb steers on a floating stick, right thumb aims with smoothing, and two big buttons for pull and push.
- Rust-and-acid duotone art, screen shake, sparks and a low bass roar when the tide climbs.
- Plays offline. Single player only - no online, no multiplayer.

A physics escape game about reading terrain instead of aiming: which beam holds, which one you can throw, which one you should drop on yourself to ride down. If you like grappling hook games, swing platformers and destructible physics sandboxes, this is that itch with a countdown attached.

Free to play, with optional ads and in-app purchases. Paid items make progress faster, never invincible: boosts are timed or single-run, values are capped and do not stack, revives cost you half a tide level, and skips only apply to ruins you already cleared. Every functional upgrade is buyable with rust scrap you earn by playing.
