Elem3nts – unconventional tower defense

My blood and tears, in the form of pixels.
Aren’t I proud of myself for this?
I made a tower defense game which does not have the traditional mechanic where towers shoot at enemies, but rather, they shoot at other towers and the aim of the game is to position those towers to victory!
