When you installed renpy, you can copy-paste the contents of "testa-win" folder into "tutorial" folder and replace similar files when you get the dialog window. Then "testa-win" option will appear in Renpy, it's the game. Worked for me. The tutorial will disappear, though, but it's not needed. Maybe you can copy "testa-win" folder directly into renpy's directory, without destroing the tutorial.
