I always wanted to make an easy mode hack for this game. I beat in back in the day, and don't remember it being that difficult, until I revisited it years later. The water is a pain, but once you figured it out - it's passable. The bell ringing part always pisses me off though, as it was easier in the Genesis version.
I think (IIRC), in the TGCD version you get knocked back more than in the Genesis one (or maybe not at all in the Genesis one).
