I did manage to get it working!
Problem was, I was directing my console to the exe, when I should have been directing it to the blender folder.
It runs surprisingly well for me! A little choppy, but totally playable.
I just could not manage to tap space fast enough to be able to do anything to the boys.
I might suggest assigning the QTE command to something other than the spacebar? Personally, I find the spacebar hard to ‘mash’ on like that.
But still, using two fingers and both hands and tapping space at about 350bpm still doesn’t seem to do much 
Also, it seems that either the zombie girl is bullet-proof, or the boys don’t know how to go for the head (getting shot has no effect, I assume you’re supposed to die if you get shot too many times?) I was able to walk through the whole level (I think?) and just ignore the boys and I was just fine.
But hell, 5 stars for atmosphere and mood! Excellent lighting, great textures, perfect music. And OMG the teddy bear…poor lil’ fella’…
Keep it up! The world needs more ‘imaginative’ zombie games like this.
