Almost, but not quite - what you included was all the assets and other materials that Unity uses to help you put together your game, but not the final, finished data itself. Unity performs some weird magic to turn the scripts and other things you use into a compact form to go with your game; it's that folder you need to include. In the location where you built the final game, there should be another folder with the game executable called SoundBlockPlay_Data. That's the folder you need to include, not the Assets/Library/other folders from the Unity project. :)
