AMAZING APP, just one small problem.. – VR World for Google Cardboard Review

This is the best vr app I have ever came across and I highly recommend it?, there's just one small problem in order to move in the game you have to tap the screen, sadly my headset and Bluetooth controller does not have that option, so I was just wondering if you could make the play button on Bluetooth controllers also trigger the walking action that would really help especially for people who do no have the button on the side of there vr headset. Other that that this is my favorite app keep up the good work :)
