Purpose of the Project

Create a short RPG which tells a story through a series of conversations with non-playable characters in the game. Utilize multiple segments to allow the entire game to written into a single executable file. Develop a system for storing information about events and their corresponding locations.

Basic Premise of the Game

You were running late for a very important engagement. On your way home, you noticed what looked like a good shortcut, and decided to take the chance. When next you are aware of your surroundings, you are no longer in this dimension. You have become trapped in another dimension with no idea of how you got there and no idea of how to return.
     Dimensional Dilemma tells your story as you struggle to find a way home, overcoming great obstacles during your journey.
