Far as the colors go, they are the same on 60Hz composite and RGB. A 
slight amount of tint, color, and brightness tweaking was needed but 
that is typical. There is no flashing or screen glitching. The sound is 
pretty good but if Mary is yelling when stung that does not come through 
  as a voice but a strange sound.

I did notice a problem with sprite crashing that was slight on RGB but 
quite noticeable on composite. When Mary runs past a tree, the green of 
the leaves and the pink of her dress turn into orange with some black 
edging. That does not seem to happen with the bees and butterflies but 
they mostly bounce off the trees anyway. Mary is definitely transparent 
rather than solid.

Looks like a great family game!
