Running flake8 shows ./juego.py:404:17: F821 undefined name 'game_over' and rightly so as game_over exists in play so you'll have to change that.

Changed that!
Thanks

Tested 98f44a4, it'll be great to not change the position of game_over and just change the indentation.

With your change, the activity starts and after the play button is clicked, the activity canvas still shows the same screen and the sound plays to tell you the game has started and after a number of failures you see the game over screen.

Nothing in the log show clearly why, but the log shows this;
