I'm on the OG rift and when i first started up game, there was no sound but thats just a common oculus problem and i got that working. Then when starting the game its going through the tutorial in the bone cage and i follow all the instructions until i get to "Use grip to grab item from inventory" and i do it but the text doesnt go away. So I try to do what the hint says and break out with the bonesaw and i grab the saw and start swinging at the weak spot but nothing happens i tried everything, but this pos game cant even get to the gameplay before it breaks.

You need to hold the saw on the side of the arrow that appears once you get close to the cutting point and then have it perfectly level while doing a sawing motion forward and backwards. Its a bit buggy but that way it mostly worked for me.
