The trilogy in the first episode was excellent, it had a secret level where you played as one of the birds; a world called Tubelectric with great music and captivating level design; and a final part with even better music that took place in a moody red castle with pretty good platforming. Many of the great tropes from this saga were not revisited later in the game.
The endings to both Jazz Jackrabbit 1 and 2, but especially the second game's ending where Jazz and Spaz team up to defeat Devan after his demon form reverts him back to his regular form, and everyone celebrates afterward happily in the Carrotus castle.
