Shockingly, Flink on CD32 is noticeably inferior to the Mega-CD version! It lacks the Mega-CD exclusive intro and outro sequences, a layer of parallax scrolling in the foreground, the animated clouds in the progress map, it isn't entirely full screen (despite the CD32 exclusive 50/60hz toggle mode) and overall, the graphics look fuzzier (as if they were slightly out of focus) and less colorful than the Mega-CD version! Moreover, it should be noted that the status bar (in the top portion of the screen) isn't integrated with the rest of the graphics, which means it ends up covering part of the viewable field and the effect isn't the greatest to look at…
Also, some levels seem to have been simplified, which means that some platforms and some obstacles have been removed in the CD32 version, so as a result the game is a bit easier. This is maybe the only plus as Flink can be a pretty frustrating game with levels that can be too unforgiving. Compared to the Mega Drive (cartridge) version, Flink on CD32 has at least much better music. In a word, if you are looking for the best Flink version, you should go for the Mega CD version. It is cheaper and easier to find compared to the CD32 version which in turn is slightly easier and definitely rarer.
