I really enjoyed the music quite a lot. There's a really good contrast between the sections that really gives the whole track some extra oomph. I found myself generally just spam-building turrets and couldn't really tell what the difference between the different types was. I also didn't notice that the enemies could take away your movement :o It was also a bit hard for me to know when I was repairing or when they needed to be repaired so I kinda ended up just placing them everywhere since usually money was not much of an issue. For some reason, I couldn't fullscreen (probably my browser) so I had a bit of trouble understanding action, but still had a good time :) nice job!
