You have some textboxes on the header of the page, you need to insert a number from 0 to 255 to select a planet, where it reads "seleccione un numero de mundo".
After that you need to insert a 0 to explore the city or a 1 to explore the world.
After that, this is optional, a number from 0 to 255 to select a background history for your universe. I didn't finish this feature but it tells who conquered that specific planet you selected earlier and when. I don't remember well.
Then you have a textbox that reads "Hand". That is, what object you currently have in your hand. You can get up to six objects: gold, lasers, book(it tells you the story of the planet), boat(you can cross bodies of water with this), timemachine(this does nothing yet), map(it shows you the streets of the city or the geography of the planet, in ASCII)
You can trade objects for other objects, that happens when you reach the end of the street.
At the end of the street also you can get an object for free (you need to guess which street)
All this if you are on a city street. If you are in the open, (the world), you traverse routes, at the end of certain routes there can be a scene depicted in the screenshots of this project. (Unfinished)
