Dokuro

Dokuro is a video game developed by Game Arts and published by GungHo Online Entertainment originally for the PlayStation Vita with later ports to iOS, Android and Microsoft Windows. The player controls Dokuro, who must save a princess after the Dark Lord wants to marry her.

The player is Dokuro, a skeletal worker for the Dark Lord. One day, the Dark Lord captures a princess and forces her to marry him. Dokuro sees the princess crying which breaks his heart and he thus decides to help her escape the Dark Lord's castle. Dokuro can flip switches to open up paths, carry the princess after drinking a potion, as well as others. The game's levels grow steadily more complex as the game progresses.
