Hurray my first complaint!
Er, yes.
That's quite interesting. Mission 2 gave me the most grief in terms of Fredding (the Colossus part mostly), however balancing wasn't a large issue. There are 2 fighter wings and a single bomber wing. What did you get killed by?
I played and tested it many times and died a few times as well. That tells me that the missions isn't easy, but I'm still able to complete it more than half of the time. Yeah, I know exactly what's going to happen, but I make allowances for that.
Oh well, just be glad you didn't play Mission 5 where over 4 cap ships warp in and shoot you with flak and AAA beams at point blank. I found that part to be the most unfair of the campaign.
Anyhow, thank you for bringing that up. I'll be sure to closely watch balancing in the future. I shall release an updated campaign eventually with more a few more bugfixes that slipped by.
