Well, since the camera focus is always on the selected mech at its center, especially at the beginning of the level it was occupying the right half of my screen mostly and the area at the far end was almost off-screen. To some extent it might be intentional not to show the whole map (but then, it's not *that* large that it's not completely shown, even when you zoom out to maximum), but the way it is it felt somewhat unbalanced on the view. If you do have that selection marker on the mechs (eventually) it isn't really that much important anymore to keep center focus on the selected one, so it would be nice to be able to pan the view around the map...
Of course, if there were more levels and there should be an element of ambush, some fog of war might be needed...
