Ok, this is not a major update, I was asleep and then I had to fly to Illiamna and back, so I’m just picking things up again now.
Flash games on the web take the form of .swf files, which are streamed by their host. The flash player won’t normally play a frame of a flash movie until all the assets used by that frame have been loaded. Working in FlashDevelop/FlexSDK, you really don’t use frames much at all, everything is done from AS3 code, and the .swf which is created is a flash movie with 1 frame. Because you don’t want to show the player a white box until everything has been loaded, normally you add a pre-loader, which is small, and which allows the flash player to show something to the user while the rest of the assets are loaded.
Up till now, all of my projects have been wrapped either by the Mochi version control wrapper, or by Whirled’s wrapper. These include preloaders, so I’ve been able to totally ignore all aspects of preloading up unitl now.
Unfortunately, as in my normal development flow I had set up my FD project as an ActionScript3 project. In order to get the FlexSDK to create a movie with more than 1 frame, so that that first frame can be implemented as a preloader, there are a few compiler options that need to be set. FD has a AS3+preloader template option, so I re-setup my project and away we went. (This really isn’t a big thing, but I lost 30 minutes because I didn’t know my tools).
Also in the line of I didn’t know my tools, if you hold shift while using the pencil, GiMP will draw a straight line!! Learning this alone made entering LD worth it to me. 
Implemented a main menu and intro animation. Next up is building/support placement and a stress heat-map. That might take a little longer, so I figured I push what I have public.

I liked being hugged, but four arms doing it is a little weird.
