It's a neat game, but after the tutorial there's so much that's not explaining. For instance, you don't really know what the new rooms do, you just create the and see what shows up, or how it'll take to get new recruits. And how many chicken farms do I need per how many monsters? what good are torture chambers and prisons? Yeah, I can make some guesses, but there's nothing in the game that tells me much.
Still, it's not a bad way to idle some time.
