This game is, primarily, a time waster. And I mean that in the best of ways.

The gameplay is very linear: gather this to make this so that you can make things further along on the crafting tree. You don't directly control your Dwarfs at any time; rather, you can assign them tasks and they do them... whenever they deign to. The A.I. will always prioritize whatever you clicked first. This means that if you want to switch tasks, you have to un-click *everything* you selected in between. Otherwise, your little Dwarfs will go about killing critters, collecting items for crafting, and building whatever you instruct them to. That's it. After all of the craft options are unlocked, you simply amass your empire. You can even avoid battle entirely if your randomly generated world has high enough obstructions between you and monster spawn points.

Pros:
Clean graphical style.
The ability to create and customize your own shelter.
Equipment changes are reflected on your Dwarf denizens.

Cons:
Linear game play without much replayability.
Craft tree could use more, exciting options.
Repetitive soundtrack.
The A.I is sometimes very silly.

Still, for the price (around 5USD) it's a good bit of fun. I haven't tried the multiplayer as of writing this.
