I love the concept but I had a hard time getting into it just from the numbers, They spawn faster than I can kill, overlords seem to take way too many bullets, where buddies die faster than teens in a horror movie. I'm sure it's fun if I can precisely and quickly kill a few overlords and get a few buddies, but I'm having a real hard time doing that.
It'd been nice if maybe the starting enemies were weaker and it got stronger once you had a chance to get a decent army. but the fact that I can't spray and pray against damage sponges is really holding the game back. I had better luck in sacrifice if I just camped out on top.
With some more time, some number balancing, some more progression this can be a really cool game.
