Because it is "classical"....

Zooming out means I'd have to set the level borders further inside so that you still can't see the end of the level.

This is not even my invention, I took the camera distance/ screen width compared to the player model size from another game where I never ever heared anyone crying about too few view range...

However I try to think about a possibility to, again, improve it, but I doubt I'll increase the view range itself. Maybe at least a little map?
