Finished Roll A Ball project, error?

I just finished the roll a ball tutorial and got everything working in the game, but when I build the game and run it from the exe all I get is a view of the horizon and nothing else. What do you think happened? Sorry I am very new at this and these types of failures after much hard work is really affecting my psyche.

at least you managed to get it to build, my project wont even build . It just says it can’t build because its compiling or importing assets or something
