Version 1.1 - Reworked code and squeezed in invader animation
Version 1.2 - Invader shots now target player, tweaked barriers, fixed disappearing score glitch

This is a port of the original arcade Space Invaders in just over half a kilobyte. I had to simplify a few things, like only having one invader type, cutting the UFO, and rethinking the lives system a little bit, but most of the major elements are there, and I think it plays fairly well.


  • Score system
  • Level Progression
  • Enemy Animation
  • Enemy Fire with homing shots
  • Destructible barriers
  • Increasing invader speed and fire rate as number destroyed increases
  • Damage system (your laser cannon changes colors after taking a hit, and will be destroyed after 3)


L/R----Move laser cannon

I was impressed even without the destructible shields.
Any chance of a write-up on how it actually works?

Thanks, had to think outside the box to get that working. I can do a writeup for that, I've been thinking about doing that for some of my tweetcart games anyway, but wasn't sure if people were interested.

The basic idea is that it's using a combination of print() and pget() as a kind of interactive decal system.
