Incredibly impressed with this so far. I like the starter choice (possibly because of my massive love for Growlithe) and I like the 'cards' theme for the antagonists. The sprites look good, as do the screenshots!
Whilst I have only skimmed it, the story and history looks very promising. You've put a lot of thought into it and taken no shortcuts which is nothing but a good sign!
However, I have a question! You say the guardians/oracles will be in random locations and that you should listen to the locals to find them. I have no objections to having them out of gyms and not being in immediately obvious locations, in fact I look forward to this specifically, but I wonder if that won't be a bit tiresome if they're incredibly far away?
I eagerly await a chance to play this.
