@Upupzealot What do you mean by Greenfoot mini? It's programmed to recognize code (a relatively simple/limited set of production rules). That get structured as Objects that get called, mimicking normal execution.

Do you mean by speeding it up? I think the time is determined by act cycles. So it's not like the greeps get to gather more when at a higher speed. Unless I'm overlooking something. And thanks! =)
