Hack for HaxBall!

Hi there!

in the couple last days i saw that there is a hack going around to gain control of a room, as in to enter a room and change the admin to yourself.
my question is, can you do it too?

the game is flash based so i guess it's not suppose to be difficult

the link to the game:
HaxBall - Playⓘ

i hope i'm not challenging you guys too much

thanks anyway!
