Read full descriptionHide 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 can’t wait to see the paths you find. Try to find the perfect trajectory for each level!
