There is a small hair of a lag on the speech? Sounds weird. Gotta be my hearing. Saying twice.
I suspect it might not be running 100% on your system. Check skip.speed with F11.
Not much you can do to speed it up currently, but netlist is always being improved and refined.
If the game really matters a lot and your CPU isn't up to the task (my i5 3.2ghz doesn't get 100%, for instance), keeping a copy of 0.223 might be good.
