The proportion of offspring that survive should be a function of the mutation rates, not something that is specified.
Shouldn't it be a function of fitness? I see no mention of fitness. Selection pressure should be based on a "fitness threshold" so that organisms below that threshold tend to be eliminated and those above that threshold tend to survive. Selection pressure should not be a fixed number of offspring that die, that doesn't even make sense.
Also selection pressure needs to vary over time, such as with predator / prey oscillations ...
and environmental fluctuations.
There is also no element of randomness to the equation. We all know that not every member of a population will have 6 offspring and that even the most fit individual can be eliminated by a chance event or the even the least fit member survive.
I too downloaded it sometime ago, but it doesn't seem to work now. I don't think it had anywhere near the parameters or the appropriate algorithms it needed to have to make it anywhere near realistic. Maybe you can make your own version of it that works

Whoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for... I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca
"Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.
Ignorance is a most formidable opponent rivaled only by arrogance; but when the two join forces, one is all but invincible.
