About

Planetary Sling

Features
Read full description

Stranded in the void, your survival depends on a single force: gravity. Planetary Sling is a fun physics puzzler where you launch your escape pod on a trajectory towards the docking station. Planetary systems get increasingly complex as you play through the levels. Satisfaction is guaranteed when you sling your pod, collect the stars, and successfully dock. The physics are smooth, yet arcade-style. Learn on the go through trial and error. Unlock achievements with full Game Center support. No ads, no data collection. I have optimized the game to run as smoothly as possible. I canโ€™t wait to see the paths you find. Try to find the perfect trajectory for each level!

About

Gravity 80s

Features
Read full description

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 โ€” 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. HOW TO PLAY - Drag anywhere to aim your thruster - Hold to accelerate โ€” fuel is limited, use it wisely - Release to coast on inertia - Use planetary gravity to slingshot, brake, and change direction - Pinch to zoom in and out FEATURES - Real swing-by physics powered by a custom Velocity Verlet engine - 300+ real celestial bodies from astronomical catalogs - 17 procedural planet shaders โ€” gas giants, ice worlds, lava planets, black holes, and more - 4 distinct map layouts โ€” solar system, corridor, cluster, and dual core - 6-category upgrade system with 10 levels each - Rogue planets and binary moons at higher levels - Real-time orbit prediction line - Planet scan HUD identifying nearby celestial bodies - Full planet catalog tracking every encounter - All sound effects and ambient music synthesized at runtime โ€” zero audio files - Retro pixel art visuals - Game Center leaderboards No ads. No in-app purchases. Just pure space physics.
