>>2761139I'm checking a longplay and will write stuff down.
1. No music other then the opening theme.
2. Different staircase, probably to make it clearer to navigate on 8bit.
3. I heard on a youtube review that it had some areas cut.
4. There does not seem to be a music room with Lurch playing,
Instead there is a door that leads to the final boss that gets unlocked once you saved everybody but Morticia.
Other then that its pretty much Snes/Genesis Addams Family.
