KC is one of my favorites. The music is just awesome. Even the short bits, like when you see the rainbow and the short tune when you see KC changing into the Nova suit. Coming from a NES to playing KC the music and sound just blew me away. The end tune in KC is one of my all time favorite chip tunes. It's just amazing.
The graphics are repetitive, but what is there is beautiful. The underworld characters are plain art.
There are a few surprises like the overworld with the Ice. On a CRT is looked amazing back in the day. My friends and I thought it looked like real ice on the screen. Had a surreal effect. (The effect is lost on emulators and clearer screens like LCDs)
Also, anyone into PC/Turbo chip tunes of course has to check out the amazing Squirrel!!
