Interesting game! I could see a more complete version of this, with some kind of pinging noise to tell the player which direction to go, or how far from the objective they are. As it is, it was an interesting experience, but after a minute or two, I wasn't sure if there was no ending, or I was just repeatedly dying when the zombie sounds increased and repeating the first few seconds of the game. I would have liked a clearer "you died" sound, with a pause afterwards. Maybe a sound that is only played at the start of the game, so that restarting is clearer? (If I was actually dying... maybe I was always having narrow escapes).
