Simon Game - play, test and feedback appreciated

Well, if I start the game and it plays/displays a button and then I click the wrong button, the game will just sit there. It should give me a message that I selected the wrong button and then play the first sequence (first button) again.

To reproduce the issue, simply Turn on game, then click start, then after the first button lights up and sound plays, click any other button.

This game functionality is stated in User Story #6 (see below):

6. User Story: If I press the wrong button, I am notified that I have done so, and that series of button presses starts again to remind me of the pattern so I can try again.

Thanks for taking the time to test. Luckily easy to remedy. Will do soon as I get a chance. Cheers.
