A way to make talking puzzles harder is alot of options, but just some of them right.
EXAMPLE:
You start with three options, one of them leads to 4-5 dialog options that's wrong, one leads to 4-5 where one of them is right, and one is just "bye".
Now, in the one with 4-5 options where one of them is correct, it can go something like this:
WRONG TOPIC 1 - Leads to 3 new options, where all is wrong.
WRONG TOPIC 2 - Leads to 4 more topics, where all is wrong.
RIGHT TOPIC - Leads to 3 more subjects, where one is the correct one, leading to success.
WRONG TOPC 3- Quits the conversation.
Now, since it would take alot of time for the player to go through all the options, the player would rather use logic to solve this puzzle.
Just my idea of hard talking puzzles.
