I finished this hack last weekend and I'm impressed. First of all, the fact that it is complete is the best part. I don't think I'm personally a good judge of gameplay so when a story is complete that is always a plus.
I liked the writing and the story. I did find myself invested into Vance and Ava's stories in the latter half.
I especially enjoyed the escape chapters and the use of generic units, I thought they were cool ideas. Difficulty wise, a few of my units got quite strong but the rest kept the game fairly balanced. Not too hard, not too easy. I felt it was just about right.
Overall, great hack. Would recommend to anyone.
