This is Amstrad CPC port of Addams Family. I can only compare it to the Amiga version that I briefly played before (which of course has nicer graphics and so on), and it seems like almost two entirely different games. In this version you often have to do some pretty fancy platforming, like for example jumping off a platform onto a ghost that's flying in the middle of the screen above some spikes, to reach a platorm on the other side. Or avoid an enemy (by jumping) on platform at top of screen, while waiting for a small moving platform below to be going in the right direction, so you can jump onto it through a small opening. But if you take it the wrong direction, you get zapped on some spikes on edge of the screen (and needless to say, there are also spikes on the bottom of screen too).
Well I've only seen a small bit of this game so far, and it often seems overwhelmingly unfair at first, but looks to be well-designed, because there's always a solution, although you may have to think about it for a bit. You can pause the game, and get 9 lives, plus 4 continues, so at least there's lots of chances for trial and error, and creative thinking. But it does require a lot of coordination too, and being able to track more than one object at once.
There's other ports too, like NES, but I haven't tried those. This one runs fine in the MESS emulator:
sdlmess cpc6128 -flop1 addamfam.dsk
When it's booted, you can type CAT at the prompt to see disk listing. Or just type RUN"ADDAMS to load the game (terminating quote can be omitted). Then you have to press spacebar at the title screen to load the game, I think, but there's a delay while it's loading from virtual floppy (too bad MESS doesn't show the disk activity light, or I missed that in configuration).
