Biffdrop is an arcade game on www.flash-game.net in which you try to collect all the white stones to clear the stages. You are a little girl who wears blue skirts and maybe you are dreaming. You are put in a deep hole where there are white birds flying to catch you. The stairs are green and the ladders are brown. There are red X-rays to stop you getting close to the white stones. And the red barriers are the baffle to cut down the way to your target. It is really a hard challenge for you to collect all the white stone. Once you finish the mission, the door of getting into the next floor will open and you can try to escape from the hole. Have a try!
