I´ve being trying to learn how to construct with objects an arrays. It´s being hard. It still takes me so long to learn each step and sometimes I get stopped in very small issues.  Now I get some of the things that I wanted, but not all. I also wanted to make small worms appeard each time the mouse is pressed. But I couldn´t finish it. They appear but very light and all of them at the same time, and then disappeared.

Well, I will keep trying!.
