If you have any interest in map drawing or worldbuilding this is a 10/10 recommendation.
Good game flow with clear instructions. For the most part, you follow along in one direction. It's very clear what you should be doing and there isn't too much page flipping. Playing the game, it feels very polished. I liked the pacing (which is adjustable) and the definitive end achievable within session. The PDF is hyperlinked together in a very convenient way, which helps with the game flow.
My only complaint is that I wish there was a more printer-friendly version so that I could go completely offline.
Overall this game is above and beyond for a PWYW product. Truly a hidden gem.
