Simple Harmonics Motion (SHM) Game Example

Here is a simple example of using circular, harmonic, and pendulum motion in a game. Precise sprite placement is a bit of a pain, but I show what one can do with a quick one level game with some random sprite placement.

See if you can make it to the end. My kids seem to enjoy it for some reason. I may make more levels.


My kids are coming up with more great game design suggestions.

  • New level
  • New palette and graphics (inspired from the MakeCode game Dungeon of the Ruthless Witch)
  • New best times leaderboard (from @richard’s blocks-leaderboard project)


  • Simpler levels
  • More sprites
  • Maybe introduce platforms?
