Looks very cool! Excellent art. Good luck. One small thing, and this may just be me. I find the tag "casual" to be a turn off for a strategy game and some others may too.
It's a tough call because appealing to a larger market is a plus but I do not think many casual gamers even touch strategy games. You might turn off the target market by trying to appeal to a larger market that is not there (casuals).
Then again you do a good job of explaining the difficulty of the game in the description.
Just my two cents though, the tag did jump out at me when I saw it. Game looks very good, best of luck to you!!!
