Premise: Protect your island lair from those pesky government agents.

My first successfully completed (for some low value of success) Ludum Dare.

It's in javascript/html5/canvas, so you need a modern browser to play it. See http://www.ludumdare.com/compo/2010/04/27/evil-lair-command-compatibility-testing/ for compatibility. In short, it works in the latest Firefox, Chrome, and Safari.

I may add a link to an improved version at the URL above, but will obviously leave the LD17 version up unchanged... Unless it really does add your computer to a bot net (hint, attempt to play with javascript turned off or view the source).

Tools:
notepad++, Gimp, Firebug, google (for figuring out how this javascript and canvas stuff works. It's been years since I wrote any javascript, and it certainly didn't have any of these weird-quasi-oop thingies in it)
