Using just the general law of gravity and Newton's second law, I created an orbital simulator.

I calculate the desired speed to put the masses in orbit around a heavy central sun, but otherwise just let the physics do the work.

Honestly, I was surprised this works due to the low-precision numbers with Pico-8, but it does!

Controls

Hold X: Trace orbits
Up/Down: Change G, the universal gravitational constant
Left/Right: Center camera on a different object

You lose if you die or if your castle crumbles.

Casting spells may be a bit tricky, but when you get the hang of it and advance in the game the right spell is always available.

Can you make it through all 25 waves and defeat the final boss!? Can you beat your high score!?

Photosensitivity Warning

This game uses some strobing light effects. If this would prevent you from playing and you are interested, I’d appreciate that feedback.

Tips

  • Read the spell directions carefully, the controls are a bit non-traditional
  • You can't move and cast at the same time
  • Slower monsters are more powerful against your castle
  • Late game: portals don't work when monsters are near the exit portal
