Problem with damaged fighters
The UI can not display all your fighters, so when some are damaged it is possible they are not listed. Hence you can not heal them. A solution I can think of would be, to put damaged ships first in the UI so you can give them healing items. The UI otherwise is good, because showing all your fighters will result in unnessecary clutter which would be counterproductive in battle.
Thx for the game and keep it up!
