It was a lot of fun playing around with the different mechanics of robo's forms (treads was definitely my favorite!) My biggest problem was with the control scheme; my fingers kept getting mixed up! With a game boy in mind, I feel quick actions like jump and shoot should always be close to each other, like mapping them to (a)Z and (b)X respectively. Then, the more technical actions of form changing and weapon swapping could be mapped to (start) Enter and (select)Shift. Also, getting shot at by objects that are not in your current view is always frustrating.
