Hey!!! Oh, gosh, it would be hard to do if you only have one 💦 Because the sound comes from the left, right, and front, and you need to press in the direction that it comes from. But if you only have one then it will make it hard to hear...
Hmmm, the big piece of advice I always give for this part is that there's no penalty for stepping in the wrong direction. So you can keep trying all the different directions (left, right, and up on the keyboard) again and again basically until you get it right and take a step. So if you can't hear where the step is coming from, just keep clicking left, right, and up over and over every time there's a sound and you'll eventually get it right LOL This usually works pretty well to get past this part (I did it to get past this part quickly when I was working on it hahaha).
