I just tried it for a bit, and I suck at this, was not having fun at all.
The world is so big, everything is hidden and your movement is so slow. I want to do some puzzles but I just can't find any. The start is easy enough, where you can follow some cables to get to some trivial puzzles. Then quite soon you'll get to a puzzle that you can't solve because you don't know what is expected of you, and you learn that if you look around you'll find smaller puzzles explaining the intention of the bigger puzzles. But then the world just opens up and you're just slowly walking through this totally uninteresting world trying to find some gameplay.
And then the controls. It's 'press shift' to walk slowly, 'don't press shift' to walk even slower, 'press any other button' to come to a complete stop and freeze until you rightclick. Doubling the movement speed and giving me a jump button would already make this a lot more bearable.
