TETHEROne-button arcade
There are no levels here to survive to. There is only the next anchor.
A wall of pure black is already moving in from the left. It is leashed to the furthest point you have ever reached, so the gap only opens while you keep going — stall for a moment and it closes over you.
The release arc
The sweet spot is drawn on your swing circle, not left to feel.
Come round a full swing, carry speed into that glowing arc, and let go inside it — that is a Perfect. Speed bursts, time stretches for a beat, and the chain multiplier climbs toward ×10, multiplying distance, grazes and Perfects all at once. Release sloppily and the chain is gone.
Momentum
Hold to reel in and pump the arc like a playground swing.
One button and a real line. Slack line is free fall. Five biomes — Dusk, Ember, Verdant, Violet and Ash — cross-fade as you travel, and the course is generated as you play, so it never repeats.
Daily course
Same course in Seoul as in São Paulo.
Every day the world gets one seeded course, plus three daily missions everyone shares. Your own best run comes back as a ghost and runs it beside you, half a second ahead or half a second behind — the only opponent that has ever really mattered.
Skins
Ten skins, every one earned by playing.
None for sale. TETHER PRO is one optional purchase that never touches gameplay, so the leaderboard stays honest.
