I've been working on my game - which has brought many new things into the engine that it needs.
A lot of the vertex / texture handling has changed, to speed things up a bit. Memory leaks have been completely wiped out now.
I've also worked in a loading screen, a very easy to handle game pausing system, and a way of making sure that a group of your commands are handled at the same time by the engine (freezing/unfreezing the drawing loop). Key and trackball events are now handled. I have also implemented a few functions to handle someone pressing the Home button, and keeping your game alive in the background.
The major feature of the next update will be an XML-driven menu system. It isn't finished yet, so is what is holding the update back, but it will be worth it. You can create very polished, very easy to manage game menu's - the transitions between menu's are handled by setting a single XML attribute. I decided to build this feature in because of the trouble I had in building my own sexy-looking menu system, I realised that if I needed to change it significantly, it would be a LOT of code to rework. By handling it all in the engine, new menu systems can be built in, literally, minutes!
Also, thanks to those of you who have been emailing in little bug fixes and alterations, I really appreciate it, and your code will be included in future version :)
