Goodbye Volcano High's gameplay mainly boils down to standard multiple-choice dialogue gameplay, where you pick Fang's responses and thus decide how they react to each bit, with certain choices leading to certain paths, with a little alignment chart showing just how close they are to each of their friends (including their seemingly more professional brother, Naser). It works particularly well here, though, especially since the options you choose from take the forms of Fang's inner thoughts and feelings. In a particularly nice touch, certain dialogues boxes have touches like fire for anger, heartbeats for romance, shrunken text for fear and more.
