AF is one of my favorite turbo games. Its tough, and exploring the mansion is fun.
I have heard some people give up right away, because the opening stage can be difficult at first, but anybody can get through it. Once thats done...you go in the mansion and it opens up a bit. You need to figure out the order of the doors to enter to collect all the things you have to find.
Its very odd, but its a basic solid platformer at its heart. You need to stick with it...certainly need patience.
The final trek to gomez is difficult once you get through the mansion, and there are some controller throwing moments. But all in all, i love AF. Still gets a lot of play.
