I'm making a game based on a book were the player at certain parts of the game, will invoke a memory to find the courage or the wisdom to get out of situation. Also later in the game, the player can transform the main character into someone else you remember using a magical artifact and another tool that points the direction to a place you remember. For instance, the player needs to get through a cave but it's very dark. The character can imagine herself as the statue of liberty and have a torch to light the way. If you get lost, you can use your magic compass to point the way. I hope I'm making sense but the main problem I'm having is how to express memories in an interface.
