My original reason for adding the obstacles, was to make it harder to score from the opposite end of the field, which meant you could score without ever needing to pass. However, I also made the arena longer than usual, so the ball won't travel all the way along it. My goal in making this map was to make Hydroball require some kind of teamwork, as well as breaking the format a bit so that you can have different types of games by using the obstacles.
