Not really posting this as to what version's better, but I remember the Genesis version of that Mickey mouse circus game being much harder than the SNES version. I rented the Genesis version when I was younger and there was this enclosing ceiling room that I couldn't finish for the life of me. A couple months later a family member bought the SNES version for me as a gift and I was like "Dang, I wonder if I can finish that room now." The room wasn't anywhere in that version of the game and I finished it quickly.
