All of what you see and hear in the trailer is actual gameplay. The game is a giant sandbox that lets you switch between creatures and objects at massively different scales, from fundamental particles to large constructs of the universe... all while reading tidbits of existential text, markov chains, and finding clips of Alan Watts recordings to listen to. Every object you "become" also gets added to a library where you can read more information about it.

It's certainly not going to appeal to everyone, but it's fun for what it is trying to do and show you. And it's not, as one comment said a "VRML demo for $60", it's a simple $15 sandbox that tries to make you think.

Bill Nye would disagree with you. Specifically, here is a quote from when he changed his mind about GMO's:

There's further details in his recent book Undeniable about why there aren't "unforeseen side-effects" from GMO foods. I think anyone with doubts or curiosity about the subject (and evolution in general) should read it.
