Oh, nice, even more kudos then; it's a lot of features for just one person! Also wanted to compliment the whole "reactor" idea – did you get it from Forts, or was it a case of parallel thinking? In my opinion its a great twist on the TD genre.
By the way, I wanted to let you know that as your main "competitor"—only other 3D game with a relatively similar visual aesthetic I've seen while browsing the tower defense category—you are a huge inspiration. I am currently trying to crank out an endless mode too, but you beat me to it...
Looking forward to the future updates!
