Stick man is a really cool concept and has some great ideas in it. There are a few things I would like to see expanded on.
For people brand new to roleplaying, there are a few bits that can really help on. Here's some ideas:
1. Examples. Particularly for doing stuff. It's quicker and easier for people to check out a small example.
2. GM Section. In this, it would be cool to put some example difficulty levels as a guide (not as a rule). Things like: "Jumping onto the hood of a moving car: 6"
3. Example adventure. Just a quick thing.
