Really fun game!
Felt like playing mini risk with D&D style dice rolling.
Recommendations I'd have would be some sort of list menu you can look at that shows you how many territories each player occupies.
It would also be nice to have some more feedback about how effective your attacking is, how many people you're losing and so on. Even just a little bit of text that appears near the hex (-1) or (-2) and so on. Really liking some of the other recommendations in the comments as well.
Otherwise, really fun! I'd love to see if this continues to go anywhere.
