here's another tip this tie for the gold cannon go nearly all the way to the top and just stay there... don't move and when that bomb blow up the particles will scatter away.... but some might hit you
i have a tip for the wall and the cannon.... first go all the way down and concentrate at the wall. when it tremors it means it will crash... by then you just kepp making a wide "V" sign and you'll avoid both the cannon and the wallo. And don't forget .....CONCENTRATE ON THE WALL NOT THE CANNON
