Another update added, this is a pretty big one. Webstart is still here:
http://www.slyhawk.com/agent00pk/webstart/Agent00PK.jnlpMay 13, 2008 – Robots added. Homing missiles added. Level selector added. Webstart custom level support added. Webstart save file support added. Bug fixes and tweaks. Sound added. Level loading optimized.
I implemented some pretty damn cool robots that are using the dumb idiot AI I had implemented for testing purposes. This makes them a lot easier to deal with than the guards, but they have the addition of homing missiles. These missiles will follow you to the ends of the earth... but can you perhaps lead them back where they came from? I'm in the process of adding "spurt" missiles as well, which will be a lot faster but easier to trick.
The app now creates a resource folder in the user's home directory. Using it, you can save your custom levels, although you can't change the background or static body images without some adjustments that will happen in the future. That's all cosmetic, though – functionally the level editor is all there. To find and share your custom levels, go to your home directory and look for the ".agent00pk" folder. And if Kev is reading this... well, maybe I decided that you had a good approach after all.

The app also uses the resource folder for save files. Whenever you finish a level, your progress is remembered. When you exit from the actual game (via escape), it will ask you what you want to name your save (temporary solution). To load your save, go to load game and type in the exact same name, case sensitive.
Sound has been implemented. My friend Bryan Highhill made two awesome background songs for the levels, check them out. He also made a short loop for the menu.
I also changed some random things, improved some stuff, etc. The control should be significantly better than last time, but it still needs a lot of work.
