Overall, I like it
A couple of suggestions:
1 - longer plot line
2 - some way to ffwd through the non-event travel
3 - choice of ships (fighters, freighter, etc.)
4 - sound
It has a lot of promise, but doesn't quite live up to it. The instructions are very difficult to understand, and I still don't quite understand how the hero is supposed to work. I agree with other posters who dislike the 1 tower type bonus structure..
