What essential episodes do I need to watch before play the game?

It's been a long time since I watched the cartoon and I barely remember the characters and the story but since this is a game where we travel back in time and revisit some episodes, what are the essential episodes to rewatch?

The game takes place during the final episode of the series. So you'll definitely need to watch all 10 episodes of Season 5.

In terms of the areas you visit in the game and the episodes/characters used:
Episodes 1-3 (Samurai Jack: The Premiere Movie)
Episode 6 (Jack and the Warrior Woman)
Episode 10 (Jack and the Lava Monster)
Episode 11 (Jack and the Scotsman)
Episode 17 (Jack and the Scotsman II)
Episode 22 (Jack vs. the Five Hunters)
Episode 23 (Jack vs. Demongo, the Soul Collector)
Episode 29 (The Good, the Bad, and the Beautiful)
Episode 30 (Jack and the Zombies)
Episode 42 (Samurai vs Samurai)
Episodes 53-62 (Season 5)

Passing nods/refrences but not necessary for recognizing story and stage:
Episode 12 (Jack and the Gangsters)
Episode 14 (Jack Learns to Jump Good)
Episode 16 (Jack and the Smackback)
Episode 39 (Jack and the Labryinth)
Episode 40 (Jack vs the Ninja)
