Interesting concept, but such twitchy movement makes it hard to play. I got frustrated failing the jump just after you get the gun. Up until that point I found it easiest to just avoid the 'enemies' and play as a pacafist. I would have expected dashing into enemies to kill them or at least dodge through them, rather than taking damage.
Love the presentation, sound and concept, even though I didn't get far enough to see the role reversal. Good job making a finished game, especially one as complete and complicated as this!
