@Andrej: I have posts going back years, so do a search using my name, and you might find some useful info. I'm not sure how relevant some of it is, though. Mine is still in development but always in rewrite. It's going to look drastically different than what is posted in the Showcase forum, but one of these days it will show up. It'll be more on the 2D side than 2.5, though. Or maybe not. It's a project in constant flux.
