It's difficult to express why I would consider this game 'perfect'. Clanker's Cavern is, by all means, a bad level. However, of every 3D platformer, this game just understands size, scope, and theming perfectly. Every level feels exciting and new while not being overwhelmingly large. There's just a loving flow to the game where you can explore a world, do everything in it (and are, in fact, encouraged to with the admittedly flawed note score system), and enjoy and soak up every inch of the game world. Banjo is the standard that control should be held to for a 3D platforming character - every motion can flow into the next one so easily and it just feels GOOD being Banjo. Banjo-Kazooie is a joy of a game to play wherein everything works together to immerse the player without overwhelming them or having way too much dead space for its own good.
