I played the new demo. Very nice. Nice changes. I did find it to be generally faster although that led me to discover that I had been playing it at apparently half speed. At 800x600 it now runs at 60fps and is much faster than I was used to, so I didn't last very long! I deliberately set the resolution to 1024x768 so that, because you have a vsync, it drops to 30fps all the time. This made it somewhat easier to play and to see what I'm doing ;-) It's pretty frantic at 60fps - but the point is, you don't have any code to adjust the speed based on the framerate.
