Portrait of Ruin features a 2D side-scrolling style of gameplay. One of the main features to the gameplay is that players can switch freely between two characters, Jonathan and Charlotte, similar to the "Julius mode" from Castlevania: Dawn of Sorrow. Jonathan and Charlotte can combine their powers to perform a powerful attack together known as "Dual Crush", and their combined abilities are needed in certain parts of the castle for them to solve puzzles and progress through the story. For example, the player must have both characters board two "motorcycles" and alternate between them to dodge obstacles to have both motorcycles intact to crash through a wall.Download : [NDS] Castlevania: PoR
