Still can't play bro :(

Just a heads up, you need to upload a compressed file (.zip or other) of your full build file, not just the application (.exe.). Unity should build everything into a single file and it should include some other stuff in that build file like a UnityPlayer.dll, gamename_Data folder and so on. The application file is not stand alone, it needs everything that is placed into that folder with it in order to work. Hope this helps a bit.

I get this error when I try to run the game: 

'The code execution cannot proceed because UnityPlayer.dll was not found.' :(
