I'm so happy to see someone use Little Lands to create their own little cute cities.
Creating my own little towns has always been my favourite thing in games like this, but sadly, as you've experienced, the game isn't very city design-friendly.
We're about to start working on the full retail version of Little Lands, since we've got so many complex ideas that we can't wait to get into.
The ability to design cute little towns; with gameplay benifits to doing so, in order to encourage it, is something I definitely want to spend a lot of time carefully implementing.
I love your use of the walls, you're the first person I've seen use them how I intended. :)
