Addams Family - Sega Master System

Video showing a full run through Addams Family , I've cut-out the backtracking but everything you need to do to finish the game is here plus the ending. The sound is god-awful so I hope the substituted songs aren't as annoying as the never-ending Addams Family loop song the game has. Does the jumping sound effect give anyone else a headache. Second worst game I've played next to Alf.
