FIRST SIGHT ON GAMEPLAY
Under the sight of the player will be just "the stuff", and with that I do mean the game element's only: no HUD, no text, no health/HP/mana bar... just "the stuff". Windows and other elements will appear contextually when you click on something
click on foe = popup with foe's info
click on your troop = window with the commands to "edit" your troop... (see [TROOP MANAGEMENT]
Each backdrop battlefield it's just a bitmap but, in order to give depth perception, elements on top are scaled down (and move slower) to look distant while element to bottom are bigger in order to looks "more close" to the camera
Certain elements on map also have some modifiers, ie: troops/foe which are walking on mountains are slightly indent up.
other graphic elements on map (obstacles like huge rocks/mountain or other building) are made to fade their opacity as a troop walks behind them.
Actually, certain area like river, forests, pavemented road and as well mountain will also effect on the game mechanic's (see: [TROOP ACTIONS]
