OK, I say I'll do more regular updates and then immediately fail to post anything for a week. Welcome to OppositeLand, population me.
Work is still ongoing, worry ye not, with the focus on improving the scripting system and I/O for the more complex objects within the world map. Also, within the main asset management system there's now an overall object dictionary that handles everything from physics objects to particle fountains, allowing them to be spawned easily in a unified way.
So yes, at the moment it's all core engine work, but this is all necessary (except for a few sidetracks) in order to achieve my current main goal of scriptable game objects.
