Daniel,
I'm sorry to say, but if the demo version does not work on your computer then the
Full Version will not work either. Most of the time you can get it to work by getting
the newest OpenGL drivers for your graphics card. However, if your computer is older
then it may not even have a 3D graphics card or it may have one that does not support
OpenGL.
Yes, you can play a GAME and all of the balls are there. However, there is no opponent yet, so it is practice for what will come later. :-)
Yes, each broomstick has a different max speed and acceleration. This means each broom
has a certain speed and agility. For instance, in the Full Version there is one that is
very fast but hard to control. :-) In both versions, there is one broom that is hard to
find but is very fast and agile.
