As already mentioned the graphics are in alpha stage 😉 And as already mentioned the engine can work in any resolution on full screen or not. The size of the hexagon is also configurable. The engine can be used to generate any hexagon grid of any size. The theoretical limit is 512 hex by 512 hex. So huge maps are planned.
As you can see the map are display on the full screen. Alright but where is the UI? Well the UI will be displayed / managed on windows. You can see two examples of windows type: the options screens (yeah not many options yet) and the unit info pop up (yeah not many infos yet 😉 .) And all windows can be move where you want. So you can make your own interface, keep open some pop ups to keep their information under the eyes.
