Immediate apologies for doubleposting.
I've played through the campaign now. I'm going to try to remain as optimistic as possible, breaking from my usual tradition of being more critical and skeptical of mission design, given you've just managed to make some actually functional missions.
This is a lot better than your usual work. The missions work. There's (usually) stuff to be done, and I've hit no actual bugs. Might be as a result of the simplicity of the missions but I digress.
My main issue is with Mission 2. You're not prompted that you have to wait for 5 minutes for your jump drives to recharge. Also, there's virtually nothing going on from neither you nor your wingmen. No reaction to what might be the biggest enemy vessel you have ever seen before. Kappa 3 on his return sounded pretty distressed and panicked, but in your mission he sort of just accepts it.
Also, please go easy on the difficulty with Mission 2. You're flying a Herc MK2, not exactly known for being fast and quick to turn, and you're pitted against enemies that ARE known for being fast and quick to turn.
What makes me curious is how these rather simple missions took you a whole of two years...
Overall, you're getting better, but there's still work to be done. I encourage more releases for the purpose of improvement.
