To give the CD version some credit, there is a really fun hidden two player mode. I forget how to access it exactly, but if you scroll all the way over the right of some level, I believe there is a flower that will take you to this special mode where you can play three (?) different mini games with two players and they're quite fun if I recall. Also I really like the CD soundtrack, maybe not as much as the chiptunes, but it's still some good stuff.
On the other hand, I believe there was a glitch in the CD version that if you ate the big meat and tried turning into the maximum pissed off Bonk, it would still display his normal sprite.
