Good enough
I suppose this will help people build some custom stuff.
However this didn't really work well as a tutorial, it seemed more like "Copy+Paste".
You should break down your code and explain what everything is doing. (Exactly how everything scales etc)
Also you should spend a little more time on your graphics. After all pre-loaders now come in all shapes and sizes.(logos getting larger/filling with liquid etc).
I know you can do better then this!
Especially after playing your game.
I look forward to what you bring us next
