The Last Monday

It is a cool quest that starts at the door of an unfamiliar house. You meet a cat who asks you to find keys and enter the house. It is dark inside the premises, and you will receive further instructions from the cat. All of them seem really weird. You will find a lot of strange things and signs here, as well as codes and doors. But not all of them are safe. And the more you progress through the gameplay, the stronger is the feeling that something terrible will soon happen to you. Will you survive?
