As you may have noticed from Luca's blog, we've decided to not only release a demo, but the script for level 1, and a way to build it.
So... what does this mean? Well, it basically gives you a chance to get a taste and see whats coming in the full release. This means you can start to build your own paths, and do your own level. I suspect we'll see a couple of new 1 file demos with other peoples scripts, and who knows..... some folk might hack it a little more and try and extend it; although that would be a little tricky and Id wait for the full release.
Anyway, I'll try and post some stuff about the scripting, the limitations and what you'll be able to do with it soon.
