no, I mean anything can get stuck on a corner. I just meant try to turn before you are around that edge you will just keep walking into the wall - not actually get 'stuck'.
you just have to make your obstacles have less 'hard' corners. Make your art have no collision, then just make a generic sprite (fill a box) with solid. And make it's initial invisibility false. round the edges of the collision boxes, then layer them on top of your obstacle art.
