Help!!! I'm stuck at the end of year 1 "face of the enemy" & I can't get..

Well, well. The first phase is the three headed dog phase. First hit the picture of the wizard in the tub. Then levitate the ducky he throws at you at the three headed dog. Then you will be able to fix the harp. After that you will be dropped underground. Use lumos to get rid of the devils snare.There will be a hoole you drop down into. The next stage is the stage with the old fashioned key. You have to be harry for this part.Levitate the little barrel next to the gold statue and then you will have accses to the broomstick the statue was holding. Get on it and hit the big key. Keep hitting it until it looses all of it's lifes. Then levititate the key into the key-hole. Now lets play chess! First keep hitting the pawns until all but one are gone. Then you will have accses to the tower on wheels hop on it and destroy the last pawn. Then get on the black horse move one space forward and the white horse will destroy the black one. Then hit one of the last black guys and he will destroy the white queen. Then levitiate allm the black queen's pieces together and hit her. Then she will fight a white guy. Next stage.... Are you ready for Quirrel/Voldemort? Avoid Quirrel's attacks. But when Quirrel sends a green head your way (make sure you have leviosa set) Levitiate the head back at Quirrel. Then(make sure your Harry) jump over the across to Quirrel and touch him. Repeat this two more times and voila! DONE. Hope I helped!
