If you beat Adventure Mode you unlock a character, and there's a randfom chance for another character to spawn on one of the maps for you to unlock as well. As for difficulty, the order of the maps is random but they could definitely be considered harder than sandbox mode for reasons such as infinite winter in one of them.
