Once you walked with your lover and it so happened that it was stolen. Stole someone's huge hand, coming down from somewhere above. But whoever you are, you must retu your love. Embark on an exciting and insanely difficult adventure and find your beloved. If you played Super Meat Boy or Kimo, then you can quickly figure it out. To move, use the arrows, to jump - the button on the right side of the screen. If you jump onto the wall and hold the jump button, your hero will stick to it and will still hang until you release the button or press the arrow (then he jumps in the right direction).
