Shitty Game. Like most Rape on Lose, the game don't reward you for winning, and if you lose, you must begin the stage with the money you had when you lose, or you must close the game and load it; Big sprites don't fit well the screen, so you must keep your people together to keep an eye on them, and if a dog reaches one of them they become imortals until killing your unit, so if you packed them, once a unit is attacked, you must contantly shot the enemy so when it finishes it don't kill another; Positioning is hard to get, they used the old beat'em up style instead top-down view, makes it hard to understand where the girls will attack, and you don't have money enough to cover everywhere, and cheap units aren't capable of defending a position which makes even stupidier their placements.
Good luck to who want to try, but sinceraly, the devs didn't even tried.
