White Screen

I am a student in User Experience and am using this for an assignment with a deadline. Creating the game was simple enough, but when I try to play the game, I get nothing but a white screen. I sent it to my instructor and all he sees is a white screen. Help.

@Superstargames That seemed to fix the problem, thank you!

@“Torrent13”, I think I may have found the problem. The first level that you enter when you first play the game is nothing but white. That’s why you see a “white screen.” Then, there is a second level that has content in it. That level does not display a white screen.

To change the order of the levels, just decrease/increase the number displayed next to the level.

(Underlined word is the “white screen” level, circle shows the current or new level order)
