Crossing the rooftops is an exact guessing gamewhen we are ready to play; after entering the name and accepting the privacy policy, the player will try to cross from one building roof to another, for this we make a long click to build him the bridge which must not short which causes the player to fall and the closing of the game is not long, when crossing if you see points below the bridge you click to pick them up then you click again to return to the normal position...a very entertaining game...!
