Meet Mad Maggie

How could I have missed that! @hayhor 

Even though it bounces of the wall, it seems to still have a decent amount of speed. They probably made it bouncing up and down in order to avoid it to turn on every small ledge.

But going up? It would be kinda weird if it didn't go up, since then you are always at a disadvantage with Maggie when you fighting against a higher positioned team...
