Unnatural uses codes which works fine. For just an unlock on a second playthrough do this.

*create password “”
*create unlock false

Add an option to enter a password at the start of the game.

*input_text password
*if (password = “second”)
*set unlock true
*goto chapter_one
Wrong password.
*goto chapter_one

Then for any choice you want to be specific to a second playthrough just use

*if (unlock)
#special option.

Then add a password at the end of your game

Congratulations on finishing the game, next time you can use the password “second” to unlock new content.

Hope this helps.
