Uh...I've never played Myst but I don't get it either. It looks like color-washed B&W forms, nothing from the natural world, nothing vibrant or interesting at all. More like being stuck in a big, empty warehouse.

I have to ask something: how can it be that both Gray Matter and this game have 1% in Steam?!
Well, a lot of people have already played Grey Matter, that might be a factor.
