I've encountered the ammo gauge bug. I think it's high time the thing got an overhaul, it just looks out of place in it's current form, and isn't nearly as readable as it should be.
In other news, I've got the golden ending. On Medium, because it turns out that switching flight models too frequently (what with testing BP, WoD and playing Diaspora...) somewhat dampens my flying skills (plus I'm too lazy to replay each of those missions 50 times
again 
).
Pretty much the only complaint is that I couldn't choose which Cyrvan missile will be mounted on my fighter. It turns out that your own Malachyye swarms are actually more of a threat than Zy ace and his wingman. While this does balance this seemingly overpowered missile, it doesn't suit my flying style too well. I'd trade the thing for a Dragonslave any day (or even better, some similar Cyrvan MRM).
