"Do you think you would use a middle mouse panning function?"
Interesting question. So the way I see it, the only reason one needs to navigate the screen to begin with is because some of the levels are larger than the display area. It does get tricky trying to quickly move flippers and blocks from one "area" to another.
Maybe you could do a "strategic" view that scales the level down to fit on one screen? That would make moving objects to their desired location much easier. The downside is that you wouldn't be able to see much detail in the penguins. But then you could always switch back to "normal" view.
Side note: I beat the "save the one penguin" level! That's all 6 of them!
