Description

AI generated. Carry a thread of courage from base camp to a lantern above the clouds. Eighteen ledges form each of three designed routes. Morning terraces offers calm, generous landings. Dusk ribbons adds moving ledges, while Windward lanterns adds gusts to the climb.

Catch a marked sky anchor, move to swing and pull to shorten the rope. Release above a ledge, land to rest and refill stamina, then choose the next anchor. Every third ledge creates a recovery checkpoint. There are no limited lives, and you can return to the last checkpoint with a time and score penalty.

Collect optional sky ribbons as you climb. Original procedural sky art, a small illustrated climber, a height rail, reachable anchor outlines and optional gentle synthesis help make the route readable. On screen controls sit directly beneath play on small screens. Keyboard controls and direct anchor tapping offer alternatives.

Save the complete climber, rope, route and checkpoint as JSON, or prepare a PNG postcard of the current view. Records are local and unverified.

Node.js is needed only for development checks. Static hosting may be supplied by the buyer; no hosting purchase or recurring service is included.

Known limitations

This is an original solo 2D browser climbing game with three compact designed routes. Seeds vary horizontal ledge placement by small offsets, not the entire terrain. Physics uses a simplified fixed 120 Hz distance constrained rope and winch, not cloth simulation or a general rigid body engine. Platforms are one way: the climber and rope may pass upward through them, with landing from above. Anchors attach immediately within 280 game units without projectile travel or obstacle occlusion. Reeling shortens rope to a minimum of 38 units. Wind is a deterministic horizontal force. Falling 180 units below the checkpoint returns the climber, and manual returns are available. Each return adds five seconds and a score penalty. Runs close at thirty minutes of climb time. Saves are limited to 1 MB; there is no automatic storage. Local scores, postcards and saves are editable and unverified. Physical touch hardware, gamepad, extended assistive technology sessions and broad browser performance are unverified. AI generated disclosure is visible in the game and listing.
