Presentation is pretty much flawless, as is the take on the theme.
However to me the lack of a map/indication of where to go (at least there are sometimes signs for Oxygen) and the inability to exit the minigames (died in the dna one in my last try) made it kind of frustrating to play.
Want to give special props for the oxygen refill sound, it really gives that feel of finally taking a deep breath of fresh air again.
