A fun idea for the theme! I do enjoy survivor-like games, too.
It was difficult for me to balance attacking enemies, mind controlling some of them and avoiding taking damage all at the same time. That's not a bad thing, of course; I'm sure I'd improve the more I play. The main difficulty I found was that I need to point at the enemy I want to mind control, but I also want to shoot all the other enemies, so I end up shooting the one I'm going to turn into a minion. I suppose that's fine as they aren't intended to be permanent, it simply 'feels bad' from the perspective of what I'm trying to accomplish.
