===discussion===
How is this game constructed?
*  '''scenes'''; Each scene contains: 
** number. E.g. <code>scene_2</code>
** title
** msg
** img (option),
** question
**  connect(ing scenes)

* html template (empty tags) that are replace as the game progresses
 
What can be changed in this game?

=== assignment===
Design a new game, that has to although existing in the Internet, has to interfere with real-life.

It has to interfere with the real world, the physical reality of the player.

The game should help the player discover the space of the square: the details, sounds, movements, the people.

Keep it simple.
Have fun!
