The entire thing plays like "Back to the Future 4" as 6 shorter movies, all tied together in one overarching plot and connected to each other. Writing, design, art, voice acting, it's like an animated movie. Gameplay is classic adventure game style however, very classic LucasArts vibes at points, some of Telltale's best work.
Of course, since Telltale collapsed, it vanished into the aether... meaning it's a game literally unavailable, worthy of playing, and fading away like a victim of a temporal paradox... time to change the present so it exists again in the future!
