Thank you for the game - and for the warm response (each '!' counts :)!

Perhaps... I actually learned something additional skills in that area 
myself, doing this.
But first I'll have to send you the latest results - I got an additional 
34% speed increase in that function today (and simplified code in 
several places)...
- I'll be back, presumably tomorrow.

Oh, and by the way: what would be helpful when profiling is if you could 
start the game with command-line options saying, "Load this savegame, 
run for $n ticks, and exit" - so that one can measure performance on the 
same amount of work :-)
