About half way through building the wall I realized i needed something to spice up the game-play a little, so i whipped out a tile-map that pushes you away from it to take away some of the freedom of movement they have, give them some things to avoid, etc...
problem was that it was janky as all get out! if you entered it from above or below it would flip you out. so I just ended up making sure the player could never enter them from above or below instead of fixing it. XD
