Works in unity, on iPhone halfway

I am just learning to use Unity and have successfully made a small walking game where I just have a character walk with a tutorial, and successfully loaded it onto my iPhone after transferring to Xcode project. Works as expected.

Next I was trying to do the same for some free assets to practice the process and such. I ran into a difficulty though. I am using this free template example. In unity I can run the game and play completely fine....
