Gravity Sling

The probe has no thrusters. You choose the angle and the power once, and from then on only the planets steer. Each planet pulls on the probe in proportion to its size, so a close pass around a heavy one bends the path much more than a distant pass around a small one.

The dotted preview shows exactly where the shot will go, including how the planets move while it flies, so the skill is in reading when to fire. Collect all the dust to open a wormhole to a more crowded layout. Hit a planet or leave the screen and the attempt starts again. Every layout is built from a real winning shot, so each one can be solved.
