Cosmos Boulders

This is a web-based installation of Cosmos Boulders.

Cosmos Boulders is an arcade-style HTML5 minigame built with reducers and immutable data in ES5 JavaScript.

It is playable with keyboard only. (It will therefore not be playable on most mobile devices, as they lack keyboards.) The key mappings are:

  • Insert coin: 5
  • Start: 1
  • Fire: Ctrl (left or right)
  • Thrust: Up Arrow
  • Rotate left: Left Arrow
  • Rotate right: Right Arrow

If your keypresses seem to be ignored, try clicking inside the canvas to make sure it's got the keyboard focus.
