I like this system! 

• Layout is really clean
• You manage a lot of content in a small amount of space, no text feels like filler
• Your procedures are nice and easy to follow
• Example town, dungeon, and wilderness sections are great ideas
• Alternate rules are a nice touch
• GM advice is great, too! 

For the game jam, how do you want us to attribute your system in the text? I notice that you don't have a license, it just says "All rights reserved."

Thank you for the kind words!

And for the jam, everyone is welcome to proclaim their adventure compatible with RR2. I need to add an explicit license for this but, while I write it up, just know that referencing the "core rules" in an adventure is fair game. I will make the text of the first 21 pages (the "demo") CC BY 4.0
