Show ship intentions as bubble on their head
When selecting an enemy ship, show it’s movement range + it’s attack range.
You select a ship by clicking on it. An outline shows that the ship is selected. Then you can drag to it to the desired movement position. A ghost ship will appear to indicate where the ship must go.
When a ship is selected (by clicking on it) you can see it’s movement area, it’s attack area and an outline around to show it’s selected. A UI panel shows when a ship is selected, a dock on the bottom of the screen, showing possible moves and abilities, and their cooldowns, and the ship’s health, and current crew.
During combat, you can see a ship’s health as a health bar (maybe). But as ships get damaged, you (maybe feature) can see some fractions. Also you can see some smokes come out of the ships as it gets damaged.
