Buried Alive

You enjoy skateboarding, sometimes a little bit too much that you actually skated on top of one of your neighbor's roof. Too bad for you, your neighbor is quick to anger and does not share your passion for skateboarding, on more than one occasion he has threatened to kill you if you keep bothering him with your skateboard. Today, as usual, you are skating across the neighbor yard but suddenly you fall into a big and deep hole. You survive the fall but your board does not and you are just wondering about how you can climb out when you hear your neighbor's voice above, then you see him carrying a block of and about to throw it down; he wants to kill you or bury you alive! But, being a street smart kid, you are not in despair. You know that if you can get him to throw enough things down there, they will stack up and eventually become high enough for you to climb out. Only problem is, you know you can't climb too high, so you need to make sure that you are on the slope side of the stack rather than on the steep side. Now how are you going to get him to throw objects to where you want them to be? Simple; he is so mad of you that he want to crush you with each throw, all you have to do is move to the spot using left and right arrow, then stand long enough and he'll throw it there; once he throw it, you can move to another position, making sure that you always have access to a slope. There are 3 different objects he can throw: stone which is hard and will stay in shape after thrown, soil which will break down if thrown on uneven foundation and sand which will spread horizontally. Take care not to get killed or buried and climb out as fast as you can!
