Hmm nice idea, give us a choice to chose difficulty of bound
for bonus cash in the game. Add some music, Make AI good, make HARD levels, a ban (should req. 3), no bs for upgrades, INSTANT UPS!!!!!!!!!!!!!!, Balanced unit attacks.
Maybe you can add a lil diff stuff to it, not just path def and bound def!
like... dice def, but doesnt take that long to beat...
