A downloadable game for Windows

Ride the currents of the cosmos. Grapple through stars and asteroid fields. Collect celestial treasures, upgrade your abilities—and remember: time waits for no one.

Quantum Tether is a 2D roguelike endless sidescroller where you swing, dash, and thread your way through accelerating space debris. Grapple onto asteroids and stars with your mouse cursor to stay in motion—but avoid corrupted anchors and the void (off screen), or your run will be cut short.

You play as a clock spirit, adrift in the celestial void. Each run echoes across centuries—your score is a measure of time itself. When one clock spirit falls, another rises in it's place, to carry on the ride of time.

How long can you last?

Built during Texas Game Jam 2025 (EGaDs at UT Austin)
