The overall feel of, and look of the game, is good. Here are a few observations from my initial games, they are not game breaking, just improvements:-
The Bonus resource icons, are sometimes difficult to tell, to which square they belong to.
Desert tiles should be more defined, from the plains tiles etc. (more, Yellow, and sandy looking)
When you click on your armies on the map, and you hover over a unit icon, a description/tooltip should be shown
When you double click on your armies, and the army panel is shown, with their abilities/perks etc. Hovering over these perks, and abilities, should show a description/tooltip.
Just had a go of the tutorial. Units during the first battle with the fire elementals do not travel to the correct square that you click on. Mine go to the left, even when I click straight ahead.
Played it again, but this time, units moved to correct squares?
Damage caused by spells/attacking that is shown, should be slowed down and much clearer
Hovering over buildings/units, in the build queue, should show tooltips/descriptions.
