I now have what I consider to be the three core region types working - footstep, click, and panic link. These are the regions involved with making the environment more believable. The other region types mostly add complexity.
I could release an Alpha right now, with just those three types and the export page working. If anyone wants to play with it, I can upload it to the SVN, and it'll appear in the next release. Otherwise, I won't upload it until I have a better feature set.
It looks mostly very good to me. It's a bit hard to make an opinion (I often see the 'Not yet implemented' message ) but what is implemented so far looks good.
Also I'd have a couple bugs to report if you want, but given it's still a very early version they might just be corrected in the next version..
Speaking of which; do you have an idea when you might release a new version?
