Hello, my name is Henrique, I currently live in Brazil and I am part of a specific group of people who deify this game. I am doing a work in the field of informatics and used as a theme the development of games and chose to talk specifically about this game. I already have a lot of information gathered but the crucial thing is missing, how was the graphic part of the game made? I mean; Sprites, animations and textures. What techniques were employed? What programs were used in development?
