Ok, I've spend a whole weekend adding and fixing based on the reports from beta 1, and here's what I've got now.

DOWNLOAD: *Removed*
Thanks for the testing guys. Additional Feedback is, of course, still welcome, but the download has now been taken down. A proper final demo version will be out later this month.
Changes :
Rather brute force fix for invisible balls.
Multiplayer is now enabled. Completely untested, but seems to work on localhost.
Mouse Sensitivity tweaked.
Menu settings can now be changed with left and right mouse.
Manual and auto camera modes. F12 changes camera, even if you're in auto mode. In manual mode, camera never changes unless you tell it to. In auto mode, it changes every time you take a shot, but also if you tell it to.
Eight Player Leagues and Tournaments ( any combination of human and CPU players. )
Sharks Mode ( one human player vs each CPU opponent in turn. )
Control overlay is now prettier, and an onscreen prompt tells you where to find it.
Oh, I don't remember, maybe a few other things too.
I'd really appreciate some multiplayer testing, as I've really no idea how/if that works.
