There is none of it.
Very sparse.
If this was a modern game, I wouldn’t be able to fall off certain types of ledges.
This was just the way it was back then, I guess. To fail, and to learn, and to try again.
Makes for a frustrating experience on one hand, but on the other, even more satisfying if you happen upon the solution yourself.
Or, in the case of clicky adventure games, WTFing all over the place.
