The original "Donkey Kong Country" game was such a success that it pretty much usurped Mario on the SNES console for the title of "best side-scrolling adventure". This sequel, "Diddy's Kong Quest", however, manages to even improve upon the gameplay of its predecessor and make for an even better gaming experience.
There are two main reasons why this game is better than the original:
1. The level designs manage to be even more interesting. Not that the levels in "DK1" were bad, by any means, but they are just more interesting in this effort. When I think back to the iconic levels in this series, I'm usually thinking of ones from this game.
2. Dixie Kong is a better playable character than Donkey Kong. The main trouble with the DK/Diddy combo of part one is that DK is such a sluggish character. He "gets the job done", but only passably for a game that requires so much jumping. In that game, Diddy is the much better character. In part two, though, the Diddy/Dixie combination are pretty much equals. Diddy is still a bit more agile and nimble to work with, but the hair of Dixie (used for flying and throwing) makes her very valuable as well.
The only reason I can't give this game the full five stars? It doesn't let you save after every level. I know, I know...gamers weren't used to that feature like they are now. But it still doesn't make it any better (at least for me). After about the second stage, the levels in this game get quite difficult. Difficult to the point of the gamer feeling a real accomplishment after completing a level (which of course is the point!). Yet, there is a clunky system of gathering coins in order to save (and even then it is only after you reach the "save point" in each stage). You may have to beat 3- 4 VERY difficult stages (often with only a few lives to work with) in order to save your progress. I don't care what the "times" were like...that makes for more frustration and less fun.
Overall, though, "Diddy's Kong Quest" manages to slide in slightly ahead of its predecessor (no easy feat). I always had a bit more fun playing this game than the first one.
