Well done!
I also agree with the reviewer on some improvements to work upon, the following in particular:
"It'd be nice to get a little more in-depth and continue the story begun in the game's opening cinematic. More importantly, a good campaign could help new players get over a pretty severe learning curve better than the hopelessly inadequate tutorials."
The original Homeworld had an excellent campaign. SoSE has the potential to top it!
