The images are only 30s of exposure time. Obviously I have to shoot more photos and stack them next time, to reduce the image noise. A better lens would also help of course.

But I am quite satifsfied with the results for a quick first try. There are a lot of visible details that are not visible with the bare eye. You can clearly see bright spots and dark shadows of the Milky Way, some star clusters and also the Andromeda galaxy.

Play FreeFall on Codepen


  • Jump from planet to planet to discover it.
  • Simulates N body gravity (but the planets do not move)
  • Play in the browser, supports mouse, keyboard, touch and gamepad input devices!

How to play

  • Use the SPACE, ARROW DOWN or S key on a keyboard or press down mouse-button or finger to begin charging your jump power.
  • You can use the A and S keys, ARROW LEFT and ARROW RIGHT or drag the mouse or the finger left and right to get the desired direction for your jump.
  • There is no other way to cancel a jump or decrease the charged jump power than actual jumping.
  • Zoom in and out with a MOUSE WHEEL. Press C to toggle between fixed camera (less nausea) and dynamic camera (the greatest force of gravity is rotated downwards). Alt+ENTER to toggle fullscreen mode.
  • Discover every planet to win the game! If you get lost too far out in the void, you lose!
  • You cannot move anything at all while floating in space. Hopefully, you land on a planet to discover it!
