One-tap orbital slingshot. Orbit a star, release at the right moment, ride gravity to the next one — don't miss.
Release at the right moment and gravity does the rest. Simple to learn, hard to master.
From cool red M-dwarfs to blazing blue O-stars. Red giants forgive a sloppy release, white dwarfs punish it.
A transparent grid curves into every gravity well — you see the same forces that pull on you.
Missed? Fall back onto a star you've visited and stay alive — it costs you your combo.
Chain quick catches for multipliers, skip stars entirely for double points.
