The wait is over - Lego Harry Potter Years 5-7 for iPad has finally been released - Woot! ...and I'm already stuck. So let's get the help thread started. I'm in the park and can't figure out how to do "expecto patronum" properly to get rid of the dementors. I can stun them, but not destroy them. The tip at the beginning of the sequence said something about charging them, but I can't figure out how to do that. Can anyone help? And is there a way to review tips that flash across the screen if you need to see them again? Thanks! Since I obviously don't have flash on my iPad, I couldn't get very far with Pottermore, so I'm hoping LHPY5-7 will give me my HP fix, but not if I'm stuck at 0.0% completed. ETA: Ok, I worked it out. Just wasn't used to using left thumb to control character movement and right thumb for wand/brick/etc. So once you've used your left thumb to get the character near the dementor, and your wheel/wand is set to "expecto patronum," you use your right thumb or finger to move the spinning circle target over the dementor's circle. When the color turns to red, take your right thumb/finger off the screen to cast the targeted spell at the dementor and that should get rid of it.
