Crystal Castles (1983) is an Atari action-platform game with an isometric view, in which the bear cub Bentley Bear travels through maze-like castles collecting gems while dodging enemies and the witch Berthilda, controlled entirely with a trackball. It was one of the first arcade games to incorporate multiple endings and a level design meant for the player's progressive mastery.
It's a beloved classic of Atari's early-80s catalog, with a precise control scheme uncommon for the era and a tone somewhere between cute and sinister that's still enjoyed today.
