It looks like we finished our project, but we have a bug, which we can't solve. Please help if you can…

When game starts, we see a poster, after clicking on it, fruits are starting going up. At times when we click on second fruit, it doesn't change the core and the fruit's costume.

Thank you!!!

Hello! I just ran your game and detected that you may need to go back into to your project and check to see if all your game code is correct. Sometimes when I create a project, I'll be done and test out my game at the end and notice some code is entered incorrectly. I can tell by looking at your project where the issues are at hand, you need to check the costumes for each fruit and check the scripts as well to make sure.When I was playing your game, I noticed that the first fruit would slice in half but the second one to go up in the air would not slice in half and then it would to continue to repeat itself like the first two. I hope you find this response helpful!
