Things to do.

1)This game should have at least 6 rooms with descriptive name.

2)The new Room rooms should be different from the rooms in the program already.

3)Create a map of your game scenario in any common electronic format (such as .pdf, .doc, .pptx, .jpg, etc.).

4) Update the source code of your zuul project to create the rooms and connections as you designed them.

5)Update the welcome and help messages to match your scenario.

The rooms created in your zuul project and the connections from one room to another should match your map. Make sure the connections between rooms are clear in your map. the connections between rooms should be bidrectional.
