By performing an effortless wall boost in the corner, you can climb the wall forever until you reach the world border. This would not be a problem; however, when you are boosting up the wall and reaching the border, you can RPG (Hand Cannon), and it will push you out the border. This will either push the player to the top of the wall or the other side of the wall. This could later be used to wall clip in speedruns or get above the world/level etc. However, this is a cool feature that could be kept for speedrunners and testers. However, it could present a flaw in level design.
