That's unfortunate... what platform are you on? How did you download the game?
It might be a problem on my end but it could be you did something wrong; I downloaded and played the game after uploading it to check for just that issue and it worked fine.
Right off the top of my head, how did you open the game? If you just open SparKade.exe outside of the folder then it won't work, you need to unzip the UnityPlayer and create a shortcut for Sparkade.exe.
Hopefully some of that helps :)
