Adventures on the Island of Despair

Isn't this Robinson Crusoe?

Is this true

Not bad, has a certain sense of character

The homepage is full of typos

It's Robinson Crusoe

Well enough??

I want to ask, what is the difference between this and Robinson Crusoe?

It's not good-looking, it's okay at first, but not good-looking at all later on.

Just pursue it,

I don't understand what the theme is trying to express. I hope I can understand it after reading the entire book.
