Imagine that : a desktop game that can play with a mouse, and a gamepad and doesn't suck !
Oh I'm sure there are tons but one that does Tower Defensy RTS and arcade at the same time ? I don't know of any.
So yeah the shop is hooked to the gamepad, the camera is now controllable which looks sick. And you can target enemies pretty well.
Have a look (VIne addict here)
