Inspiration: Drawing a golf game would've stumped me, but you were truly inspired. I'm impressed by the mechanics you developed out of the game's nine-hole survival structure. Especially the crystal arrow traveling mechanic used to traverse each region.
Usability: Once I grokked the concept I think this would be fairly easy to run. The "Quick Tip" boxed text is a nice touch, helping the GM sell the atmosphere of each region to the players.
Vibes: "The sound of rain is an illusion; It is the hiss of a thousand whispered wishes bubbling up to the surface of the lake." I love that. Very evocative.
