Android App Inventor tutoriales

Guys I have finished the tutorial. And this is the resulting App from the tutorial. It was too long. So I have to edit it to make it shorter and to remove a part when I had a problem jejeje he. So get ready soon to watch it. For the tutorial I started since the very beginning.. using Inkscape to make graphics and to get values like size and position from sprites. I will show you the full process... and you know what I like the fact that I didn't use buttons just the screen... well let me know what you think of it...
