How do you beat level 4 on Spladder

It is quite an easy level but like you, my friend, I found it impossible at first!
First of all, the most important thing is not to knock the box on the far right to cover both of the buttons.
Now, here for the proper tutorial: When you first 'jump' onto the level push the box you can see to the orange button (forget about the green one for now) so that you can get to the box on the far right. Once you have done that jump over the little ledge and under the thing that lifts up when you press the orange button. When you see the other box, you may have to jump over it to push it to the left. Push it to the left as far as you can without pushing it to the other section where the first box is. Then (the past bit might seem a bit pointless after reading this), push it to the right so that it is under the podium that lifts up when you press the orange button. Go back to the first box and jump over it so that you can push it to the green button. You will see that the podium cannot go all the way down to block your path because of the second box which is stopping it. Jump over the little ledge and, while jumping press the right button on the arrow key so that your helmet is hitting the bottom of the podium while you are pushing the box. When you are finally free, push the box to it's original position, jump ON it (not over it) and jump on to the higher platform where the spladder ladder is and you can complete the level. Reread this as many times as you can until you can understand it.
