Explosions and meters and endings, oh my!
Since the AI is working on a basic level, I decided to make the game actually a game, rather than just some sort of free-form piloting toy. It's approximately the game I was going for now. Each team starts with 10 ships, and gains two ships each time it loses. So in the final round, the winning team has to beat 18 ships with 10. Given how hard I'm finding it to win, I might soften this to one ship per loss.
The meter I decided to use is this one, which works perfectly. Additionally, I added explosions (this explosion graphic and one of these explosion sounds). It looks and sounds fantastic!
For now, when the game ends, the music slowly fades out.
