Downfall is a classic made point & click adventure game which was made in the Adventure Game Studio engine. It was released earlier this year. I feel that this is a game which is completely underated and unheard of apart from the AGS community.
"Quiet Haven Hotel was supposed to be just a one night shelter for Joe and Lucy Davis. But things soon start to go wrong. Lucy's panic attacks get worse and soon she disappears. And in the morning hotel changes too. Nothing is what it seems anymore. Joe is left alone, trying to understand what is happening, trapped between reality and the nightmare. Then everything changes again and the world turns black and white. Only the colour of blood is still red...
And it's all around him.
While the raging storm outside gets worse by the minute, it turns out the hotel isn't completely abandoned. There's a party on the third floor... but the birthday girl surrounded by her silent guests just keeps crying... The doctor in room 202 is hearing voices coming from the walls telling him to perform a certain experiment... And one girl who is asleep in her bedroom is dreaming a strange dream that soon turns into her worst nightmare..."
