Oddworld: Abe's Exoddus is almost everything you can hope for in a sequel. It stays true to the original in terms of imaginative story and interesting art design. Also the mechanics are a very organic progression on the original game, allowing you more voice commands to interact with other mudukons. As well as posses pretty much every other creature you come across, then enjoying their interactions with the world and creatures from their perspective. New animals and environments are introduced as well as more cinematics. All in all its a great sequel to a great game.
Having said that, I have some gripes. As mentioned by the developers this game feels a little rushed. The puzzles don't have quite the same mind boggling difficulty of the first game, there isn't a lot of trial and error in order to figure out how to progress. There are good puzzles but it feels like they have gone for quantity over quality in this game.
The voice acting and character dialogue feels much more... goofy. Its still fun and quirky but the original game felt much darker in comparison, even though it was also very silly in places.
Finally, a personal gripe of mine, in the first game Abe's voice commands would trigger certain responses from sligs, now the sligs just respond with "What?" to every command. A bit of a shame, not sure why they took this out. These interactions were a fun little Easter egg in the original.
