"Innocence R" uses altered and improved features and elements from the original, including character displays, the "awakened" character state, and the skit, title, grade and cooking systems. The dungeons are rebuilt, featuring new puzzle elements, switches and the need to push boulders to form pathways and unblock passages. An extra dungeon tied into the extra story content is also added. The game uses an altered battle system under the name "Direct Interface LMBS", which includes a fourth playable character. During battle, the characters can be directly commanded using the PlayStation Vita's touch screen. A second Mystic Arte is included for the old characters and two new ones introduced for the two extra characters. After each battle, characters earn Ability Points (AP). AP are used in each character's skill tree by purchasing abilities and stat boosts. Each character has their own unique skill trees. Another additional element is the "Rave Gauge": players can line up different artes in the battle menu, then unleash them all at once on an enemy during battle. An arena is also open to players, where cameo characters from previous "Tales" titles can be fought.
