Great concept! I liked the AI pathing. Considering the levels are randomly generated it's very possible to get your "minions" stuck in places and in 30 or so levels it only happened like once or twice. (and that was me actively trying to get them stuck) I would recommend you change "special attack" into mind control or puppetry as I didn't understand "team up with enemies" meant take over them.
Also I don't mind reading the controls on the submission page but some reference in game would be nice, icons on the HUD or an in game How to Page would be nice to have.
Finally as hard as it is to hit enemies sometimes, I think special attack could have either a larger radius or if you are concerned about mind controlling more than one enemy from that, a used on successful control. I depleted multiple charges trying to get one unit and went through several levels solo as a result. (That or increase the frequency of mind control charges throughout levels)
