I'm possibly a little late to the party, but I just wanted to reach out to say a big thank you for a brilliant and innovative set of super-quick-to-the-table rules.
Player-facing dice-pools make for a really engaging experience for players (rolling dice is an integral part of the RPG experience, after all, so the more the merrier), the usage-die mechanics just feel right, and the combat is quick and deadly - as it should be. I can see the influence of Cairn, Knave, and Maze Rats that you list; however, to my mind this system is much better in a lot of ways, giving meaningful and flavourful differentiation between weapons and the like, yet without feeling any heavier - it would definitely be my preference.
I particularly like your elegantly simple system for being wounded where it's the relative difference between your Power roll and the excess damage (after armour etc) which determines the outcome injury-wise - it makes a lot of sense on an intuitive level: very nice!
Great work!
(P.S. anything else in the pipeline for Wyrd?)
