It wouldn't be good to explain too much about the game's storyline, because a lot of the game's interest comes from untangling the mysterious horrors that lie in wait in the mansion. All these horrors are seen from the point of view of a little girl, the daughter of the mad scientist... and he is very violent.
The game mechanics are pretty simple. You just explore the mansion, talking to various characters you meet along the way, picking up and using items when necessary, and unraveling the mystery surrounding your father.
Mad Father is a horror game. By its compelling environment and storyline, this game will keep you glued to the screen through the length of the adventure.
