About TetherRun

TetherRun is a momentum based platformer. You run, jump and dash through a course, and you can fire a grappling hook from each hand to swing across gaps and over spikes. Speed carries from one swing into the next.

Every run is timed, and your best time becomes a ghost that runs alongside you on the next attempt. There is also an online mode where everyone races the same course at the same time, and the fastest clean run wins.
