Here is my first game that im trying to make. Its almost done just need to make option to stop it and then to make it restart not sure how to do that and i added code for restart button in lines 29 to down and changeScene function from line 168 in order to restart scene with click on that button still not sure how to stop game and scoring when time is up its possible i have some errors in those 2 functions and probably need to add some code for this to work. Can anyone help?
