- fix rotation whilst moving jitter - no idea what the cause is.

- fix falling through ramps/jumping off ramps tradeoff - 

- add fx to gun firing - impact sparks. (Impossible - need cvs version to get spark position.)
- retest and rebalance bullet force impacts when impact positions are correct - current rotation should stop.
- consider adjusting damping factors to be mass independent.

- add crouching, inc. it not going away if something is above you. (Resize cylinder, on expansion check space against sphere for collisions. Need cvs version.)

- add player reset key, to return player to start. Bored of falling endlessly on failure.


- arrange for correct startup/shutdown, so it can transition levels.
- add progress bar support, inc. load time caching. (Maybe.)
- add loading screen.
- go through and add more customisation capability, especially to player.
- clean up coments etc - get to tutorial quality.
- add design overview, intro doc.
- do licenses, inc. media.
- arrange for packaging, i.e. creation of installer.
