How do you shut off the "electric form" of your ball?
Or did you make the game so that you can't shut it off?
It simply wears out and can't be shut off manually, as it is. After it wears out, you become vulnerable until the ball becomes green again and you can once again create an Electric Ball. I suppose I can change the mechanics, but it'll probably alter the gameplay quite a bit.
Also... could you increase the window space? Enemies tend to just pop out of nowhere and you only have a split second to react to their appearance.
The resolution is already pretty hefty for an indie game (1024x768)... though I suppose that some form of smaller view, or making the objects smaller, might do the trick.
