Really nice game! I was a backer, and have been playing this for a while. It's a solid game that leaves you with a really pretty dungeon at the end. What was so amazing to me - I'm definitely not a drawing wizard - is that you're busy filling out these small boxes, and when you sit back and look at the whole you're immediately surprised by how cool it looks.
Good to note that this is not just about drawing: there is a "tower defense" element to the game as well where you have your dwarves and beasts battle it out against monsters coming u from the deep (colored cubes in my case).
Can't wait to see the other titles in this series!
