Super Mario 3D Land: depth perception

I'm up to world 5 now, so over half-way through the standard list of eight (though I suspect, given other Mario titles, that there may be more hidden).  It has got better, but I'm still not finding it amazing to play - it just feels a bit awkward to control at times and I'm finding it tricky to see which plane Mario's actually standing on when it comes to some of the side-scrolling sections.  Even with the 3D effect on maximum, some of the platforms blend too much into the background, especially on the cloud sections.

Still, I've collected lots of star coins, have around 50 lives to spare, and have no intention of dropping this game half-way through.  It helps that I've got a nine-hour flight on Friday ...
