easy but hard to get three stars

I can't fire, even though I'm following the directions. What's worse, though? Hijacking my effing right-click menu and not giving me a graphics quality toggle. That's annoying as heck, and p[eople really need to stop doing that. Leave my right-click menu alone.

I can't fire.

Nice, though if I shoot a ball in the end of a level, after the killing ball, and it doesn't detonate before winning screen it will stay and explode after hitting retry and thus make it possible to clear a level without shooting any balls. Just so you know.

The controls don't work. It's unplayable.
