One thing - I think the first time I engaged enemies I couldn't switch commands left + right, but the second time it worked fine and I fired some missiles. Mistake on my part?
Even if it was you, it was me.
Even I have a few issues telling if I've selected something or not in the combat screen, which may be what happened there. Alternatively there are a few similarly-named booleans controlling the whole thing, and I have mixed them up at least once before in my code.
That one mission isn't nearly enough, I need more!
It would have been very possible for me to include more than one, but by the time I finished I was just too tired to generate the content that would have been needed. It's a shame, because I put a lot of work into finishing the game's handling of ejected pilots and expended missiles, but there's no way for you to see that it works.
Ah, some nice advice there. I've added it to my to-do list.
Ultimately, I'd really like to make the combat much more graphical than it is now, perhaps even with little radar blips circling around shooting at one another. Though that may be a little beyond my abilities, I'm afraid. I definitely agree that the whole combat experience is a little overwhelming and unclear. The chief piece of work on the finished game will be to figure out how to do that well...
