It's a cool concept, but nobody except grenadiers are really controllable. I think it would be a lot more manageable if there was a way to regroup units and keep them together, as opposed to all spreading out. I'm also not sure if I'm doing something wrong, but I can't kill enemy bases. They get to 0 health but they keep spawning units. I also think spawning units with the keyboard would be great, since you wouldn't have to move your hand between the keyboard and the mouse. Either that or let you move the camera with the mouse.
