No problem. Had a couple "caught by spam filters" too. These things happen and unless I'm sleeping, it should be dealt with immediately.
I include a "Demo" main.lua in all my packages that demonstrate how to use the libraries (except for game templates, of course, as they ARE the demo. :). For EnViRo, tapping the screen will cycle through each Scene. Once you look over the small amount of code it takes to do this, I'm sure you'll start to get the hang of how it works. Slightly more detailed documentation is being worked on and I'll ship them out just as soon as they are complete.
I am also working on graphical designers and everyone will be notified and given access when they are complete. :)
For EnViRo, take a look at EnViRo_Lib_Default_Set.lua. Make a backup copy, of course, and start playing with the parameters. Change some colors, swap out some images, change some speeds and I'm sure you'll start to get the hang of it. Next, add a new Scene to EnvScenes.SceneNames, copy one of the existing Scenes, rename to your Scene name (you'll see the pattern) and start putting in all the elements that you want (copy them from the other Scenes, swap out images, change colors, sizes, speeds, etc).
I can't wait to see what people create!
