Thanks for the feedback. Let me first address the screenshot issue. Those screenshots are extremely old. If you look at the name of the program, in the old screenshot's, you'll notice that the game say's "working title". This was WAY before any maps were even near completion. The buildings do have walls, doors, etc. Check out the demo, and you'll see. I'll be posting more up-to-date screenshots soon. The dungeon is supposed to be cloudy with sand. In the actuall demo, you'll notice the flying sand & rock, as the monster shakes the dungeon.
Now, as for the installer, I found it a great and easy way of installing Liberta. I find it better than the classic ZIP file. But, I might phase it out in a later release.
I also find the characters rather cool. I will use character generators to make more, but I feel that they look great, and are nicely sized. I'm also trying to show that you can create a massive world, with many maps, and still use the default graphics. That way new users are not ashamed and picked on because they like and use the RTP sprites.
