Eureka moments!

 

After spending the last few days getting frustrated with this game, today I finally managed to get it to do what I wanted. I was starting to think that my nicely planned project timeline was about to get messed up as I wouldn't be able to finish the changes to the game in time for this week's lessons. But thanks to this youtube video I am back on track. The game now has 2 levels and new backdrops featuring violins as requested by my students. 

After watching this video I changed from using a 'when I receive this message' block to using a 'when the backdrop changes to' block to move the game onto level 2 and that fixed the problem.

Here's the finished game, ready for the second cycle of my project to start on Tuesday.
