I’ve decided to try the Tarquin Engine. I know ActionScript, but if the Tarquin Engine can save me some time, it’ll be worth it. I’ll have full access to all its source, which consists simply of a .fla file. I’m hoping that if it doesn’t allow me as much flexibility as I want (and it probably won’t – nothing ever does), its framework will still give me enough to work with, that it’ll be worth tweaking and modifying it. Enough analysis for now, though. Now comes the trial and error – the only real way to know.
