Donkey Kong Country

The Good
The game has excellent music, even for today, and character movement is spot-on. Add to the fact that the game's level design is very good, varied, and distinct (I never got the feeling that I was playing the same or similar levels over and over again like I do with, say, Sonic) and you got an superb platformer.

The Bad
The graphics is where the port is not quite up to the SNES version (especially backgrounds). While I can understand the saturated sprites to make the game visible, there is no good reason to have flat backgrounds.

The music lacks reverb effects (as in the SNES version), but this is hardly noticeable unless you are listening for it.

The Bottom Line
One of the better platformers you can get your hands on. If I'm to compare it with something, it would be a combination between Mario and Sonic. You got a bit of Sonic's speed and Mario inspired level design. The end result is a game that (IMO) is better than both (Not that I've played every Sonic game in existence).
