Who would even play this game ??

Haha, you should know, Amnesia and Penumbra are the scariest games you'll ever find on our earth.
I really recommend, play both of them - to the end. It will be a fantastic experience for you and you will begin to love this games!
Perhaps you should begin with the Penumbra series (Overture, then Black Plague, and then Requiem). This game is a better experience than Amnesia, more puzzles and story. Even a bit more immersing because of plausible environments etc. But you also can start with Amnesia, buy the game - your money will be good spent! And you will enjoy every single dollar in it.

The "deformed guy" is just the beginning. The whole game will be even 50-times scarier! No joke!!!
When you have fear, then you will enjoy the game most. Because the goal of Amnesia and Penumbra is to scare you to the ground.

You should not quit such excellent games. Play them, slowly.
