A step back from the first game. You're basically getting the exact same experience as you got in the original game. The challenge went down sharply from the original, especially with regards to the platforming aspect. The ending felt like anything but, and I was stunned when the credits started rolling.
I don't usually consider graphics, but this game had some definite issues, most notably:
Several places where the actual floor doesn't match what is represented as the floor, so you end up standing inside the floor in several places. The biggest issue with this being the snow world where Y.E.T.I.s would be completely concealed inside of a snowbank causing you to be attacked seemingly out of nowhere.
