+## kedilayanaveen10: Solve each piece of the puzzle!
+This level can be broken down into multiple small tasks. Solve each of them independently and get past the level.
+
+1. Get past the initial ice.
+2. Escape the gravity outside.
+3. Reach the water.
+4. Cross the water.
+5. Escape the zombies.
+6. Get the yellow key and reach the next chamber (escape the ice again).
+7. Get the blue key and exit.
+
+
+Solutions for each step:
+1. Place an invisible boulder to stop sliding just before the ice ends. (Place it at (1,10))
+2. Place invisible boulders till the teleporter in the middle of the map. (Place from (3,14) -> (26,14))
+3. Now you reach the teleporter. Go inside it and enter again into the teleporter from where you exited to reach the water compartment.
+4. Again place invisible boulders to stop falling into the water. (Place from (27,14) -> (38,14) skipping the place where a boulder already exists)
+5. Move the zombies left whenever possible and create a passage along the right. (Place a boulder on top of the first zombie to make it possible for other zombies to move left)
+6. Remove the code which adds the boulder here.
+7. Remove the code which adds the boulders blocking the path (Remember not to remove all the boulders. One boulder is needed to cross the water)
+
+Code:
+Zombie behaviour:
+```javascript
+var player = map.getPlayer();
+var x = player.getX();
+var y = player.getY();
+/*Hint: There is a me.canMove method for zombies, for example if me.canMove('right')
+is true, then it means that the zombie is able to move right at that specific point in time
+//Hint 2: You can specify where the zombie will move with ex: me.move('right')
+*/
+if(x > 40 && x < 45){
+ if(y >= 13){
+ //make the zombies move left to clear out way for player
+ if(me.canMove('left'))
+ me.move('left');
+ else
+ moveToward(me, 'player');
+ }
+}
+```
+
+Placing boulders and invisible boulders:
+```javascript
+//do not remove this boulder; it is needed to cross water
+map.placeObject(30, 14, 'boulder');
+
+//place invisible boulders to reach the teleporter near water
+//and cross water
+map.placeObject(1,10,'invisibleBoulder');
+for(var i=3; i<=38; i++)
+{
+ if(i==27 || i==28 || i==30)
+ continue;
+ map.placeObject(i,14,'invisibleBoulder');
+}
+
+//place boulder above a zombie to make them go left
+map.placeObject(map.getWidth()-9,map.getHeight()-2,'boulder');
+```
