Played Exoddus on the Playstation, and it kicked my butt like no tomorrow. Thankfully, the logical structure of level and puzzle design makes sure that you *can* beat each challenge. Rescuing every last Mudokon, however, is clinically insane to attempt without a walkthrough.
The oddball sense of humor is sometimes fun, and sometimes jarring. Still, nothing else looks or sounds like Oddworld games, and that's ultimately Exoddus' greatest strength. Oh, and no box puzzles. That's definately a plus. :)
