Really interesting, imaginative writing. "◆ A miraculous healing spring lies at the root of the asteroid." may be one of the great rumors of all ages. I'm very intrigued by Mud + Lasers now!
I ranked this lower for gameability for the same reasons I love the writing--it's a VERY evocative and specific setting, but feels hard to play with because it's written in such a dense and interesting way. Gene Wolfe style!
This makes me want to check out more stuff you're working on, and I will!!
