If you're playing a seated PSVR game with a controller, you're likely to sit a certain way, and hold your controller a certain way. Tarsier Studios was able to take full and total advantage of this knowledge. They are able to use IK (Inverse Kinematics) to create relatively believable  arm and hand movements.  Of course, in this VR puzzler, your hands are trapped inside intricate contraptions. The detail on the boxes containing your hands can actually be hard to comprehend at times. I'm not sure I've seen a single PSVR  title with graphics as clean and crisp. As for the audio, the sound design is subtle but extremely effective. As the  lab scientist clicks his pen repeatedly, you can practically hear his disdain with every annoying click.
