Thank you very much for your comments (:
Since this is for my Master project (in video game Design and Development) I have deadlines and that is whay I made things more quickly. But I intend to continue and perfect this project, because I feel that I can do several things better but because of the time limit, at the moment, I cant as I would like.
I am Mexican, thats why I chose to be inspired in different cities of the Mexican Republic, since it is something I know and Im familiar with.
