City of the Daleks - Glitch

Yep, I have found a glitch! Towards the end, when you play as Amy and you need to put the blinder thing inside the Dalek Emperor. Before you enter the room turn directly to the right and walk forewards. Amy will fall down a level, through the floor. And she will be in the visuisar room! Once here you can walk about. and the plants won't snap at you. And the Daleks have no green light, so they can't shoot you. They don't even notice you! Sadly I don't have a video but... to get back up go back into the visulisar room and examine the control panel underneath the big eye. Suddenly the doctor will appear, and the scene replays (the one where you make the blinder thing) and you play from there!
