In this week’s ABF level 3 and 4 rovio walk through shows using bird quake I have just had 185 attempts and not once did it do what the walk through shows, also they unleashed all the power ups so that you could use them all at once that as just stopped and gone back to 2 only can only assume it a rip off by Robin to get you to buy more power ups. Disgusting think I might stop playing.
