You can't play this game on a mac because it requires that you hold down the left button while clicking the right button, which doesn't work on trackpads.
There should be a free play setting where you can set custom settings. In this free play, you should be able to also turn off whether points matter or not. This mode can be used as practice or play with custom settings.
Not a tutorial, just a popup screen that explains the buttons. There may be one, I just missed it. If that's the case, I'd suggest making it more evident. I didnt even know there was a jetpack.

 "Soccer Physics"){kind=icon}
 "The Dragon Warrior"){kind=icon}
You mean like a video? Edit - I made a gameplay video instead. The game is to simple to have a tutorial at this time. But thanks for the feedback!
