The VR implementation is more like playing a xylophone than a piano really. You smack the keys with your hands. Nothing groundbreaking compared to, say, beatsaber, but definitely playable, and it's all suitably weebshit music. The tiny bit I played of the puzzle part of the game is disappointing in VR though. You're just pointing the laser at things, and if you try to walk around or even take a few steps, the game blocks out your vision with "outside play area", so you can't even look at the props.
