Hey man sorry for the ignore, I didnt check the forums in a while.
First of thanks for thinking along and trying to improve!
You had some realy great ideas but I'm not sure if I will add them to the map. I do agree the tiki village can be a little better but I think a small village fits the map better than accual buildings like a pokecenter. The huts could be better decorated though, I might look into that later, for now I'll leave it to the players themselfs.
I'm realy glad you looked into the npcs and confirmed they can be included in the map. I do think your prices are a bit off though (1 gunpowerd for an ultraball??). But I will try to set up some NPCs and add them to the map soon.
