speed, reproduction, and defense. Everything else is a waste. Once you can sequence enough of everything else, then you able to walk all over everything.
overall a great game. So long as you don't click before the windows move (possible on slower computers), then most of the glitches won't show up. 5/5. Well done.
sometimes you get a "go" button, even though you want to fight. Happened to me one time when I was trying to attack a city. It just said "go", I had no other choice. Then it went past the city and never came back. Had to reload... :(
if you upgrade the swordsman, the miners, and the cash giving castle all the way, you can get past the first part of the game without too much of a problem. After that, upgrade your giant, then your archers and you're golden.
you might as well make the ammunition unlimited. I never even came close to using half of my allotted ammo. Also, while I get the point of the glock doing more damage, than say the uzi, in theory both bullets should do the same, since we're talking physics here. Also, the quick drop of the bullets and bounding to do damage was game physics success, reality let down.
I think it would be a great improvement if the minimap showed signs of changes in the world, so that you could check the status with a glance instead of having to move all over the place.
