I found a bug while i was joking around where you can transform into a ball shape.
Head, arms and legs folding into the upper body but you still can do all kinds of stuff as long you holding an item in your hands!
That means you can transform run around and also shoot people while in this stage.
The only thing is, some people can see you just normal and others see you in the transformed state. It seems like only people in a certain radius around the transformation area are able to see you transformed.
