This is great! I like how the text doesn't imply the need for a GM, while letting you have one if you want.
I think a simple play example would be helpful, for instance explaining how a character would succeed or fail in a situation where they have applicable tags vs no applicable tags, especially if they have low Kismet.
I could picture myself becoming over cautious after rolling a 19 or 20 and not participating much. Unless I was told that I don't risk much rolling for something my character is really good at, essentially resetting my Kismet at a low cost.
The game for me would be to find such an opportunity for a low risk roll before danger shows up again.
