TETHER

Hold anywhere to fire a tether at a rope point ahead. Let go to fly. The rope has no length limit: any point ahead of you is in reach. ↻ (or R) restarts a run.

Swing low, release on the way up. Release rising and fast for a PERFECT: bonus points and a climbing combo. Hit ×8 for OVERDRIVE and smash through hazards.

The floor is lava. Watch for laser walls (one gap), yellow speed lasers (no gap; break them moving forward at speed 600+, a boost ring always comes first; the speedometer turns yellow when you're fast enough), saws of every size (some on chains or rails), drones that wake and chase you once you pass, rockets (a flashing ! warns you), fire spouts from the floor and ceiling, and gravity wells that drag everything inside them down.

Boost rings launch you forward and make you float a moment. Purple rings (rare) flip the world upside down until you fly through the huge purple ring that follows. Green pads launch you high off the lava; pink bumpers fire you away at twice the speed you hit them; updrafts lift you without stealing your forward speed.

Power-ups stack on the left of the screen: shield, magnet, ×2 score, slow-mo (slows the whole game), jetpack (hold in the air), extra life, reel (hold to pull the rope in), heavy ball (swings harder and smashes saws and drones) and phase (pass through anything).

Modes: Classic, Daily, Co-op, Race, Time Trial, Zen, Hardcore, Low Gravity, 60s Sprint, Shard Rush and Power Gauntlet. Ten biomes, each with its own weather and soundtrack.

Shards from runs and missions buy orbs, trails and items in the shop. Your best run races you as a ghost.

Online: tap ONLINE, pick a name, and you land in a lobby listing everyone who is playing. Challenge anyone: they get the request in-game and can accept or decline. Once they accept you both pick an orb and trail, hit READY, and a countdown starts a 2500m race on the same course. Crashes cost 1.6 seconds, first to the line wins, and if your opponent quits you win.

Two players on one screen: player 1 on mouse or ↑, player 2 (green) on the space bar. On a phone, left half is player 1, right half is player 2.
