HOOK. SWING. FLY.
BEAT THE CLOCK.
A high-speed, one-thumb platformer built for pure momentum. Fire your grapple at glowing anchors, whip through ruined industrial megastructures, and race against the developer record times.
Everything that makes you go fast
Designed from the first prototype to give speedrunners frictionless controls, instant feedback, and infinite routing possibilities.
Pure Momentum Physics
Hold to hook the nearest anchor, lift to release and fly. Reel in at the apex of a swing to build kinetic speed and slingshot through gaps without touching the ground.
Real-Time Ghost Racing
Every personal best run is recorded and replayed as a transparent ghost runner. Chase your past line, diagnose lost velocity, and shave off valuable milliseconds.
Beat The Dev Medal Times
Every course features official Bronze, Silver, and Gold medal benchmarks. Matching Gold means you have equaled the developers’ own personal record runs.
Instant Restart Flow State
One tap immediately resets you to the start beacon with zero load times. Designed from the ground up for speedrunners who demand instant rhythm.
Two-Thumb Ergonomic Reeling
Keep your thumbs in position at all times. Fire and release hooks on the screen while your right thumb toggles the high-speed cable reel button.
100% Offline & Private
Zero sign-in required, zero forced accounts, and zero internet connection needed. Save files, ghost replays, and medal times remain safely on your device.
4 Unique Industrial Environments
Each district introduces distinct terrain, hazards, and movement dynamics.
Cyber Ruins
Crumbling megastructure towers above toxic sludge pits. Learn basic swing arcs, high-velocity releases, and boost ring entries.
Molten Foundry
Intense industrial heat, synchronized laser barriers, and hydraulic crushers. Requires split-second grappling and momentum preservation.
Storm Docks
Gale-force ocean winds, swinging cargo cranes, and razor saw blades. Slingshot through narrow container gaps over the crashing tide.
Frozen Spire
Sub-zero glacial updrafts and falling icicles. Master vertical cable reeling to conquer the ultimate ascent to the mountain peak.
Captured Live On Device
Explore actual high-speed runs framed across modern iPhone displays featuring Dynamic Island and notch architectures.
Master the Grapple
Hook onto glowing magnetic anchors, swing through crumbling industrial towers, and release at the peak of your arc for explosive momentum.
Two-touch control,
zero visual obstruction.
Most mobile action games clutter the screen with on-screen D-pads and joysticks. Grappling Speed Runner uses full-screen gesture zones designed so your view of upcoming anchors and hazards is never blocked.
Left Screen Touch
Hold anywhere to project your grapple line to the nearest anchor. Release to launch forward with conserved angular momentum.
Right Thumb Reel Button
Hold the dedicated REEL trigger to reel in the cable during a swing, converting swing radius into blistering forward velocity.
One-Tap Instant Respawn
Hit the top restart button to reset to the start beacon in under 5 milliseconds. No countdowns, no loading delays.
