Dr. Langeskov, The Tiger, and The Terribly Cursed Emerald: A Whirlwind Heist Review (Μueiwn)
I played my first playthrough, delibrately going slow and standing around listening to the narrator plead with me to do things, and I finished in about an hour. It took me another half hour or so to do another one and a half runs of it to get all achievements. You can get 90% of the dialogue and entertainment in about a single, twenty minute playthrough.
If you played The Stanley Parable and liked it even a little bit, then you should give this a try.
The gist of the story is that you are behind the scenes of a the single player game "Dr. Langeskov, The Tiger, and The Terribly Cursed Emerald: A Whirlwind Heist" and since somebody else is playing it, you can't. Instead, the unseen narrator guides/tells you want to do and when, because most of the workforce has gone out on strike because of reasons. For example, he tells you "turn the knob to activate the rain", and you can sit there and wait for however long you want to turn the knob, while he pleads with you. You can also find other levers and buttons to push to mess with things (though the story progresses regardless).
It's a nice way to spend an hour, and wouldn't mind spending a couple of bucks for it, but since it's free, there is literally no reason not to play it. There is no replayability with this game, but that was the same with The Stanley Parable, once you've seen and done all the options, that's all there is to the game. Same thing here, but even moreso. "It's not the destination, but the journey" but taken to the extreme, the journey can be completed in 10 minutes and the destination actually made me chuckle the first time I played it.
=================================
The graphical options could be better (only four options from poor -> best, with a unity launcher with resolution options), but I had no problem running it at a locked 60fps at 1440p with SLI 980s. Probably not the hardest thing to run, even though it looks really good. It also helps that there isn't a lot shown at once, and you're locked in a room, so heavy optimizations can be done on the developer's end. Though, at one point there is an open flame and fire shown, and that stood out as being drastically lower quality. Other than that isolated instance, I was not disappointed with the visuals. There is a bunch to look at, boxes, posters, and papers all had really high resolution textures and could be looked at up close to read about the game that you're backstage from. There's a lot of information in the scattered papers and beta review sheets laying around that give you an actually fairly high detailed view of what is going on in the game that you're not playing. (though, granted, you can choose to ignore all that and play the 'behind the game'-game instead).
TLDR; Don't ignore this game because it's free, thinking it's low quality trash, nor brush it off because it's trying and failing to be a The Stanley Parable-clone. It's well made, with a great sense of humor and a great narrator, just like The Stanley Parable.
