I had an interesting idea while playing this. Was wondering if instead of getting a lump increase in speed after X amount of buildings, have it increase a little bit every time you purchase a new building . Might help move capitalism along a little better.
Great game but humans need a weakness. It's a little silly that nothing is effective against humans. Lets burn him to a crisp...that didn't work, lets electrocute him...well screw it double slash is pretty much got that covered
