I just played easy mode. The only thing which isn't right there is the hint system, but if someone uses it, he doesn't need easy mode to begin with.
All easy exclusive stuff seems to work just fine. Well, maybe except when Wally's turning out the light, it is accompanied by a slurping sound. Not exactly what the dialogs suggest. It's probably in the scripts that way, since in Adlib, that sound could be anything.
If you want to try, I made a patch which forces the game to run always in easy mode: http://www.mediafire.com/?20wqej2wk2y
Put the patched monkey2.000 and monkey2.001 to classic\en\
To undo it, just removes the files from classic\en\
