Your little spaceship never stops moving in Nova Hop: it circles a planet on an orbit ring, and the only question is when to let go. Tap the screen, click, or press Space to hop off, and with good timing you latch onto the next planet’s orbit and keep traveling.
Scoring rewards nerve. Each planet passed earns points, but skipping a planet and landing on a more distant ring adds 100 points for every one you jumped over. Waiting has a price too, since each full lap around a planet takes 10 points away. A level holds 20 planets; clear them and the next one arrives with fresh kinds of planets, extra hazards and higher speed.
On a keyboard, P pauses, M mutes the sound and R starts again after a game over. A good rule is to leave on the first clean opening rather than circling for a perfect one. Another one-button timing test is Geometry Lite.
