Hmm no problem like that for me.I keep hearing about how in the beta, it is hard to distinguish between characters and backgrounds, could someone elaborate?
Most recent game I can think of where I had a similar problem was with Sonic Generations. I only really had this problem once with the game (very beginning of Green Hill Zone with Classic Sonic) but that time when I couldn't figure out where Sonic was on the screen really pulled me out of the experience and annoyed me as I tried to keep my eyes on him. (thankfully that was only a few short seconds in the first level in the game)
You do sometimes get lost in the insane amount of chaos,but you get use to it.
Hopefully they make it easier to keep track of your player.
