As a fan of Warhammer 40K, X-Com, and turn-based games in general, this really appeals to me. Playing the demo a bit, it really had me looking forward to seeing what the unit attacks were going to be like, the music is really strong, and in general I just have to say nice work!
If I could offer up a couple thoughts, I found the scrolling to be problematic; there were several times when I just wanted to move the pointer but instead found myself scrolling.
And just as a suggestion, I found it harder to read text when it was on backgrounds that had horizontal lines on them. Instead I think to maintain a bit of interest while increasing readability, the backgrounds could have gradients but with complimentary colours used (complimentary to the text colour).
Nice work, looking forward to seeing where this goes.
