Here's a port of a PlayDate project I made. It's a solar system simulator!

The PlayDate SDK uses Lua just like Picotron does, so porting wasn't too hard. This version of the project has color of course, plus semi-decent mouse support!

Original project here: https://robotinker.itch.io/orrery

================================================

Put the solar system in your pocket! Orrery is an astronomy/astrology app written for the PlayDate handheld (https://play.date/). Crank through time to see where the planets were or will be on specific dates. Includes:

  • Scientific mode: a 3D view with realistic orbits
  • Diagrammatic mode: a simple, compass-like view of the solar system
  • Astrological mode, including:
    • Zodiac annotation
    • Retrograde planet detection
    • Lunar phase
  • Controls for easily jumping forward or backward in time by decades or centuries at a time, and the ability to jump to the current date as well
  • A save system for bookmarking specific dates
  • Delightful sound effects!

Really nice! The visual style reminds me of the system map / navigation screen in Frontier: Elite II.
