Can you notice this issue?

I happen to be making my own top down movement thing, and there is this thing where you can bump a corner, even if you technically shouldn't? Not sure if it is worth looking into, as I don't notice in much myself, but what you do you guys think? [2JC3F3CJ] Cpad/dpad to move, R will slow down the game, Y will bump you up and to the right a little (I don't recommend doing this unless R is held.)
