Hi Nin Nin (can't find hats on my keyboard!)
Cheers for your help - just out of interest, does VNS 1.2 allow you to increase and decrease variables by more than 1 at a time? And does it let you add one variable to another?
I thought a command like ADDVAR=a,3 (adding 3 to a, for example) would have been a good addition.
So do you want me to send you the whole game to look at? I worked out that it is accumulative memory leaking that causes it to crash, so unless V1.2 addresses that, I'll probably stick with splitting the code into two separate programs and linking them with a password.
