You Are The Dwarves… who have delved too greedily and too deep

Usually, this is a bad thing.
Ludum Dare 25 ~ BEGIN!
Welp, a Tower Defense map wasn’t quite what I thought would fit within the realm of “You Are The Villain” but I think I’ve found a great idea! In Tower D’s, generally you strike a balance between upgrading your current arsenal, or advancing your technology to get access to better weapons. Well, being a fan of the Fantasy genre, I’ve decided to make a dungeon crafting tower defense.
Dwarves love digging, and digging always gets you to the heart of something evil. We’ll start out our tower defense with basic towers (rock throwers, hammer traps), and as the game progresses the Dwarves dig deeper. An unknown evil resides within the earth and at some point you gain access to eeevil towers. The deeper you dig, the better towers you get!
Unfortunately, all that digging releases demons that try to escape into the world. If you don’t kill them, you end up losing the eeevil essence they took with them.
Let’s do up some art and see what my crappy dwarves look like!
