The Dark Room (YouTube)
To put your mind at ease, you will not be eaten by a grue in The Dark Room, but as you struggle to escape from this fiendish and hilarious YouTube-based puzzler you'll probably meet with a number of other unfortunate ends. Such as accidentally gouging your own eyes out, electrocuting yourself on a light switch, or growing a really unattractive beard. And all the while, you'll have to deal with the taunts of Australian comedian John Robertson, who has some choice words for your promiscuity with walls after you grope in the dark for the light switch. "Now even the walls don't respect you. And they are capable of respect, but not for you. Not anymore."
At the risk of tautology, dark room is dark. You can't look around. You can't check your inventory. You can't go north, or to Southampton. You could try weeping, but that might not get you very far. You can't even see your own tears. It's a dark room. You might try thinking outside of the box, but... "Thinking outside the box would only help if you were inside a box, but you're not, you're here. In The Dark Room."
If you've never played a YouTube game before, the game relies on annotations (pop-up links) to lead you from video to video. Most of the endings require nothing more than a determination to click everything clickable and a sharp eye for hidden annotations, but the "100% Best" ending does require downloading a certain video and performing some basic editing on it, something that is possible to do with freeware you may already have. (Without spoiling too much, the "Best" ending isn't actually that good for you as a character, as you might expect from the sadistic host, so the satisfaction of it is more the sense of accomplishment.)
Robertson made the game as a clever self-advertisement for his comedy shows, and for the most part it functions to advertise himself simply by being wickedly funny. There is one video labeled "sell out" that is an explicit advertisement, giving dates and locations for upcoming shows, but you can certainly just skip that video if you're not interested. The language is fairly salty, and there is described violence, but visually the game isn't offensive, so you'll be alright with headphones on if you have to consider others in the room. The experience is somewhat akin to You Find Yourself in a Room but the antagonist is rather a good old-fashioned human bully, albeit wittier than most. Robertson has also been adding more content, such as a Valentine's Day section, and the "Best" ending promises a sequel, so this is definitely a game to watch. But you can't watch.
Because you're in The Dark Room.
