Basically you're HAL 9000, but not an antagonist. Mostly it's a narrative-focused walking simulator. I say "mostly" because most of the "puzzles" are just the same as all the other tasks: press the buttons you're told to press when you're told to press them, over and over. Except that suddenly out of the blue one or two of the puzzles are ridiculously opaque or tiresome. Normally I hate anything walking-simulator-y, but they actually pull that part off (mostly). A lot of the things you have to do are just involved enough to engage you. Sometimes the press-buttons-in-sequence-ness would just make my sigh in frustration and broke my immersion, but less than most games like it. So the game starts off pretty well... but the controls are so clunky, unresponsive, and sluggish, that it quickly becomes a massive headache to do anything. The worst part by far is the controlling of cameras, which is what you spend most of your time doing. See other reviews for detailed breakdowns of this.. it's awful. The UI *mostly* has a very nice visual design, which is a shame since the usability on PC is often pretty crap. In my playthrough I ran into multiple bugs and found many parts of the writing to be pretty baffling or completely stupid. I have a long list of complaints about all sorts of things that aren't worth writing here. TL;DR: I don't recommend it. It's one of those games that manages to do most of the hard things right, and messes up the easy things. Most of its more severe problems could be easily fixed, but clearly won't be :(
