First of all, THANK YOU for including sound and music volume sliders!
I really like the premise of this game. Seeing a hero's journey from the incompetent villain's eyes is a nice twist. The execution of the game, however, made it pretty difficult. I think the main mechanic of the minions shooting at the hero is at odds with what feels good when controlling a character. I didn't like how when I stopped actively moving a minion, they would turn around and shoot at the hero. I understand this is part of the challenge of the gameplay, so I'm not sure how I would suggest changing it. Maybe there are more minions to control, but when you leave them facing a certain direction they don't turn back around?
I also thought it would be nice if the minions could shoot each other. That was I could body block bullets with another minion. This would create another potential solution for the difficult "double minion spike maneuver" you mentioned below.
It was a bit quirky, but I enjoyed playing your game!
