Raging Loop is an interactive visual novel with a branching plotline, in which the player's choices affect the direction of the story. Certain choices reward the player with keys, which can be used to unlock additional choices and explore more of the story. A Scenario Chart allows the player to return to any given scene or choice. There are four main endings, as well as many bad endings, some of which are optional. While the player has some freedom to explore different paths, the main endings must be played in a linear order due to the locked choices. Many of the game's choices are at key moments in the Feast of the Yomi-Purge, a Werewolf-like social deduction game in which characters attempt to find the identities of the "wolves" hidden among them.
