I've decided to make this revised beta public, mainly because the quantity of feedback from the closed beta wasn't very good. The quality of feedback from those who were able to play and responded was excellent, and has helped me fix a lot of issues and add a couple of new things.
http://sybixsus.blitzhosts.com/bbbeta.exe - SFX 7ZIP - No installer, no registry, no junk. NOTE: You WILL need to right-click / save as in order to get it to download.


Screenshots are all out of date, so I'll update later, but this is the most recent.
System requirements are hard to judge. I've been told it works surprisingly well on a P3-700 with a TNT2 videocard in it. It's unlikely it will play acceptably with less than 16mb of videoram, as AGP thrashing will probably kill it.
For those who beta tested, this is what has changed :
THE FOLLOWING CHANGES, FIXES AND ADDITIONS HAVE BEEN IMPLEMENTED:
1) Bug where pin would land upright in the gutter and not be recognised as "down" is fixed.
2) Camera Transitions may now be turned off completely in General Options
3) Loading Screen Added to Challenge Mode
4) Loading Screen now recognises the right and middle mouse buttons as well the left.
5) Jittery Action Replays Improved ( maybe not entirely fixed, but definitely improved )
6) Bug where some old shadows would not be cleared when skipping bowling animations is fixed.
7) Mouse is no longer centered at every stage when configuring your match.
8) Tool Tips for Graphics Options ( VERY small on windowed screen, but nice size in-game )
9) Particle Effects can be turned off in General Options
10) Shadows are now disabled by default.
11) Player Configuration Screen now uses a smaller font to ensure there are no overlaps.
12) Standard Control mode now has render tweening to keep the speed up on low-spec machines.
13) Added the ability to play all Challenge Games and Level in Arcade Mode
14) Fixed small rigging bug with Ayame.
15) Score Display system completely rewritten. Some text display effects have been sped up.
16) Mouse pointer is no longer displayed during shot control phase.
17) Graphics Menu is now only shown on startup the first time you run the game.
18) GUI Text rewritten to fix bug where mouse cursor was not recognised as being "over" a piece of text when the mouse was over the gap between two characters.
19) Beta Expiration Bug Fixed.
THE FOLLOWING CHANGES AND ADDITIONS HAVE NOT ( YET ) BEEN IMPLEMENTED
1) Add Shadows to Pins : Very slow on even the fastest of machines. Too many copyrects for Blitz to handle, I think.
2) Display scores directly on monitor texture instead of a GUI overlay. Doesn't seem to give me the kind of flexibility and readability of the overlay.
3) Increase Difficulty Level in general. Easily done, but waiting for more feedback before this is implemented one way or the other.
4) Decrease Difficulty Level. As above ;)
THE FOLLOWING BUGS WERE REPORTED BY ONLY ONE PERSON AND CANNOT BE REPRODUCED. THEY ARE BEING KEPT FOR FUTURE REFERENCE :
1) Game Crashes when skipping camera transitions.
2) Game Crashes immediately after selecting the alley.
