Wow, fantastic game! Truly unique and a very well-rounded experience. The main menu is awesome, and it's so cool how you can rotate the map up and down. The connection system is great too. As for the art style: Seriously strong 2D pixel art! Great job! Might be one of the best I guess?
P.S. Someone like me needs some more prominent feedback for the runes. Well, maybe that would get annoying later when you have a lot of them, but I kept forgetting to use them every few turns because I was just staring at the cool design! :D Maybe if you don't use a rune for like 10 seconds, it could start blinking?
