Samurai Jack: Battle Through Time is coming to Switch on Aug. 21st, 2020, and hopefully it'll do the series justice. Game Director Hiroaki Matsui certainly believes it will, and he also thinks the game will provide quite a unique challenge. He shared his thoughts in an interview with NintendoEverything.
“The game has a flow for the player to acquire many skills while proceeding with the play. Jack’s mobility, physical ability, and battle technique will be expanded as the players continues through the game. Naturally, the degree of freedom as a warrior will increase, but in higher-difficulty modes, more challenging enemies are waiting for the player, so I’m sure even hardcore players can enjoy the game up to a fairly challenging level.”
Tackling the game's challenges on normal difficulty should take you about 10 hours or so. That said, you won't be able to unlock all the collectible items and skills with just a normal run-through, so Matsui hopes players will try their hand at the “Master Samurai” and “Master of Masters” difficulties.
