I've posted an updated TileEngine Technology Demo to v0.6.3 for dowload on the Soap Dragon Games website.  The new version look very similar to the old v0.2.3 one but there are a lot of changes behind the scenes, including heaps of scripting updates, dialog box handling, dynamic buttons (which can be created in lua script), multiple player actors and switching between them, and a bunch of other improvements.

It also includes a (semi) working map editor, but you need to know some script commands to make it work.

Jump over to the site and download it.  I'm keen to hear any feedback that you have about it.
