EDIT: I was shtoopid and didn't post the level.

I spent over an hour getting the yellow and red buttons covered, and I just cannot see how else I could have done it. What am I missing?In the process of getting both red and yellow buttons covered, I could not prevent one boulder from going into the bottom room. This, in turn, caused the one boulder to move down, preventing me from getting the bonus coin in that room. If I get the coin, I can't cover all three buttons, and vice versa.
Push 3 down and 1 up. Push 2 right and 4 down. Push 5 right and push the box up. Wait for the boulders to collide and then push 5 right again. Then push 2 down.
