oh wait its a co-

valve back at it with some good, reliable and fun cancer

This..ahem..Visual Novel completely changed my perspective on VN's.

First of all, obey the content warnings. This IS NOT a wrongly tagged cutiepie VN. There is disturbing content involved.

But otherwise an amazing game. Mind you, it does take some time for the 'Twist' to happen but when it does, oh boy are you in for a ride.
I also suggest that you keep your game files open and play in windowed mode. Sometimes, files pop up and then disappear.
Also keep an eye on the actual dialogue. After finishing a first playthrough i suggest you play it over again with a 'Fresh Install' and read through the dialogue. The references provided about the game's hidden nature are subtle and go over a first timer's head.
Another thing is that the game doesn't really end until you get the credits.
Lastly,
