I just wanted to say that this has some of the most exciting character classes I've seen in a game. I loved how they are each categorized into what kind of play style they are for. That's super helpful for new players.
My test for most systems I encounter now is, "Can you play as a Fairy witch riding a wolf?" (my wife's character she came up with), and I think this is the system that seems the easiest to find something comparable.
I also like the Druid one, which I usually play in DnD 5e, so that gave me hope that I could have a not OP version of that class in an OSR game. Tempted to try running this now that the OGL drama is in full swing.
Edit: Also, I love the death system. This is a great way to let players choose between "death makes a good story" and "I want to live forever!"
