Tip for Nagoya 2nd Wave for Non-Archers
Close to your side of the fight, there is a barrel touching the bottom of the screen. Go to this barrel or die; these Ninjas can nearly oneshot at all levels. Wait here, and when one comes to you, simply turn around and fight them one on one(Turning before one gets to you makes you step, and if you get one on each side, your dead)
Great game, but could have been more. Could have been armor upgrading, and the army management could have been better. When placing with the reserves, there should have been an option to "Swap" or "Add". I would put older units in the reserve after conquering a new place, and having to go to the end of the reserve list and place them got annoying.
