Hmm, I clicked on "Start" on the main menu, but then the screen turned white and then nothing else happened. The music plays, but the screen just stays white. I'm using Safari web browser on my Mac OSX 7.5, if that helps with anything for troubleshooting.
I have the same problem as futfut. It won't load for me; all I see is a white screen. I have this problem in both Google Chrome and Safari web browsers using my Mac OSX 10.7.5.
I read the same book about a year ago and made the same game from the book. I never thought of uploading it here though. It was a really good book. So I give you 5/5 stars for learning from the book, but 1/5 for originality since you added the orbs and the lights beneath objects, XD. If you like, check out my first original Unity game, Memory Thump, that I made after finishing this same tutorial. You can click on my profile to find it. Unity is really awesome, but I keep coming upon limitations that seem to make it nearly impossible to do certain things.
