The Gryffindor players will follow your mouse. Press 1 to change into Angelina Johnson. She can pick up the quaffle and score by touching the opposite goal posts. It can get stolen by touching the keeper or any other Chasers. Press 2 to change into Fred/George Weasly. He is immune to Bludgers, which take away 10 points from your team if you touch them. Press 3 to turn into Harry Potter. He is the only one who can catch the Golden Snitch, the small yellow ball. If you touch it, you get 150 points and the game ends.
