Artwork and writing are top notch. Also always a sucker for the classic game turned rogue like. It would be cool to see more upgrade paths, as a lot of the current upgrades don't seem like they really change how you play, and more focus on just rewarding good play. I'm also not very good at "Go" (or however you call it) so I could just be not noticing this part of the game due to lack of experience with the game.
Really cool game!
