TETHER

TETHER is a one-button momentum game. Hold to grab the nearest anchor, let go to fly.

Holding reels you in and builds speed, but an anchor snaps if you hang on it too long, so you have to keep moving. Release at the bottom of a swing to go far, later to go high.

There is always another anchor in reach — the course generator guarantees it, and the test suite proves it over 300 seeds and 78,720 anchors. It also proves the game cannot be beaten by holding the button or mashing it: good play travels roughly twelve times further than either.

One self-contained HTML file. No dependencies, works offline once loaded, installable, and playable with one finger or one key.
