As I said, I don't think I'll pick this up, but I do think it is an interesting experiment in game design. Game design has been stuck in a bit of a rut for decades now. Platformers, RPGs, and fighting games haven't changed in terms of basic design since the NES era, and shooters are still working from the basic Wolfenstein/Doom formula.
With the tools we have available today, and the easy availability of funding, it's easier than ever to make a game, and we're staring to see more and more independent studios pushing the boundaries of what defines a game. Some of those experiments fall flat, but even those are pushing us in a new direction in terms of how we look at and play games.
It's a very exciting time!
