What a neat twist on the area horde survival genre. It's an interesting mechanic where not only do you have to position yourself in order to not die, but you also have to position your army to attack and defend yourself. An RTS where you the commander can die is a very intriguing concept that you could definitely do a lot with.
I wish I had a bit more control over my army since most of the time they formed a sort of conga line whenever they were targeting enemies. Also, after a while the orcs would keep spawning and going towards the center and the game started to lag. I was able to just run away for a while and try to pick off single orcs in order to level up my army, but it took a while and I would get laid out by the orcs anyways.
But besides that little bit of imbalance, I still enjoyed the game. The little character pop-ups that would appear were nice and I liked upgrading my skeletons to put hats on them. I also thought it was funny how you could upgrade the orcs too and totally screw yourself that way. Nice work and nice polish on this game keep it up!
