I'm only a few stages into it, but so far so great.
There are a few things I personally would like to tweak on the controls. First, I would want to have the default movement for soldiers to move in attack mode (stopping and attacking if any enemies get in range) instead of moving to the destination first and then attacking (make that be the mode that requires pushing a button). Second, since I have a mouse with a wheel, clicking the center button to pan the map will sometimes make the screen scroll up or down. I would rather pan the map with the keyboard, but it's tough to hold the mouse with one hand and use the arrow keys to pan and use the number keys to select squads and use the A button to move in attack mode all at the same time. If it were possible, I would have WASD pan and have a button other than A switch between attack mode and moving mode.
Also, in case anyone complains about lag or choppy play: switching browsers from Chrome to Firefox made a HUGE improvement for me. Even though the FPS on the display was a little lower in Firefox than Chrome, I could actually tell (or feel) that the game was running much more smoothly in Firefox. (I know, I should have quit using Chrome for gaming ever since they stopped supporting Unity, I'm just a slow learner.)
