Gravity Dot is a space physics puzzle game where you pilot a tiny dot-ship through procedurally generated solar systems using only planetary gravity and a limited fuel thruster. No waypoints. No autopilot. Just you, inertia, and gravity. ARCADE MODE Progress through increasingly complex solar systems. Use swing-by maneuvers to navigate around planets, avoid black holes, and reach the target star. Drain its energy to clear the mission, then spend earned energy on upgrades at the Hangar. 3 lives per run — one wrong orbit and it's game over. ENDLESS MODE Explore an infinite universe with no fuel limits. Absorb energy from any planet for score and drift as far as you can. Unlocked after clearing Mission 5.
