Nice to see an RTS game, man that brings me back (RTS games such as RA2, Emperor BFD were some of my childhood favourites xD). Nice work on this, it was a little unclear how the energy worked at first but I got the hand of it, though a thing to improve is the fact that I could just build outside the AI base, a build radius would stop that xD, that and the air force disappeared on attacking and tanks navigation got stuck now and then. Other than that its great, good work!
