I'm really having fun with this game! It is turning out a lot better than how I expected. Here are a couple of things I thought of while playing through the campaign. I hope this helps improve some things. Great job!

Some important things come to mind. There has to be a quicker way to get out of top down city view mode once you're done with that.

In order to view the stats of a unit you have to double click really fast and hold it on the last click, and then move the mouse cursor to the page it brings up.

Game really needs an "Edit unit" button.

There should be a prompt saying "Please end turn" whenever all your moves are up so you can keep going.

Lack of any tutorial makes things a little unintuitive.

Pop up notifications are a good thing, like in Civ 4. There should be an option to turn on letting you know when things are built.

There should be a random button for the unit design (The "Other" part)

The "hmm" grunts get repetitive sometimes. It reminds me of Exile (that old windows game, I think it's called Avernum now). I think there needs to be more "acknowledged orders" sound effects.

In-Battle Autoresolve. Where you see the battle occurring instead of either manually doing it or letting the computer do some random number thing to decide who won.

Bonus to this: You won't have to do the above if you include a drag all window in the battle screen.

Getting to the equip screen is a pain.
