Glad you got it working! Not quite sure what might have been the problem... Could be an issue with the game engine itself just being finicky.
You may need to turn up your volume (and make sure you're using headphones) in this part! My main piece of advice is that there's no penalty for stepping in the wrong direction. As the surrounding noises start to make it harder to hear, you can keep trying different directions until you get the right ones. Let me know if that helps!
