What about making all the levels as equally zoomed out as the Alien one?
Here's another major thing : could you add some extra code that remembers the last level you were on? That way, when I leave a stage, I'm not automatically returned to the first one?
Of course, we could imagine an even more sophisticated system, where the stages have their own menu screen, which would appear every time after at least two characters have "left the screen rightward." I'm not passionately asking for it, but, I do like that idea as well. At minimum, some sort of stage memory script.
These are things I would like to fund!
