I decided to download this, seeing as how I am very excited about it's release, and had a few things to say, and also a few questions.
I have to say, the editing tiles portion of the new kit is alot better then before. You added alot of great feature to enhance the production speed/value. It was tough fiquring out where everything was, but I do understand it's just a preview.
I didn't, however, fiqure out how to even create a map.

It was hard, and I think it kept on crashing... I'm not sure what the problem is, but I did find that when I went to edit a layer, and select a background tile, the value of that selection kept on restarting back to -1. I'm not sure this is why I couldn't create one or what. I was really dieng to check out the new map editing window
I'm still looking at the other things, but those are my first impressions thus far.
By the way, it's a good thing and a bad thing you released this.
Good: We can see what's to come.
Bad: Now I can't wait even longer, in fact I was trying to create a new game, only to remember it was a demo.
EDIT: I didn't see the test project. Maybe it's just me who can't view the maps...I'll try to see if I have the correct drivers or what not that I need.:?(noticed it doesn't matter if it's negetive one)
