space invaders tutorial

I've finally just about finished my Space Invaders tutorial. I started it in Semester 2 last year, with a Year 10 class and recently have been developing it further with a group of year 8's. Here's a screenshot from version 2, the clowns become more menacing as they advance:



For more details about how to make the game, screenshots and downloads of three game versions, see my website. It is released under the Creative Commons license, which means you are free to use and modify but please acknowledge the source. Feedback is appreciated.

Here are some advanced features incorporated into version 3:

• Create a controlled relentless advance of enemies (serried ranks or phalanx)
