Make the game easier to understand. I don't even get it at first glance.
That was in the work in the last couple of days, as I been listening to feedback for the past two months! However, the new stuff aren't yet deployed.
1) I added a help page. You can access it by pressing "h" while the menu is open in game mode. This explains what's going on in term of interface.
2) I added tooltip which allow you to identify what you're seeing by hovering over any tiles. You will be able to identify units soon too!
I could construct a tutorial on how to play, but given a lack of gameplay features, I think it is too immature at this time. You wouldn't be able to do much anyway. Plus, I don't have a framework for tutoring just yet. They need a trigger and goal detection system first.
Even more, a tutorial probably can't be perfected on the first try. It will probably be confusing and people will give up in frustration.
That's why feedback is so important! If everybody is silent, nobody tells him why it is wrong. Whether or not you donate, speaks up! I like to know.
