I think I will take this into a proper prototype because I had fun with it :).
The main mechanic was going to be if you sneak around the zombies they would stay somewhat dormant but the more you attack them the more aggressive they become, so I was enticing players to kill them because they are zombies but that would be a detriment as they progress (do unto others etc)
Unfortunately I have not finished that programming as you would of seen haha, but on the side I splashed in the survival golden rules but it wasn’t supposed to be the main focus.
You are correct, they cannot hurt you yet, you can only die if you jump off the edge haha.
And as for the music, I feel my greatest skill is in music / sound then programming, and no art skill haha.
Thank you for the comment and for playing :)
