Your goal is to let Tux's spaceship move by changing the mass of its surrounding planets. Don't get too close to the planets or you will crash on them. The arrow indicates the direction of the force on your ship.
Is an t-amas gun toir thu gluasad air an t-soitheach-fhànais aig Tux le atharrachadh air tomad nam planaidean timcheall air. Na teann ro fhaisg air na planaidean no buailidh tu riutha. Seallaidh an t-saighead dhut comhair na cumhachd air an t-soitheach agad.
