Get one of your three balls to the end. I understand the title a little wierd but it was not my intent. I couldn't think of anything else. Use [LEFT] and [RIGHT] to move. Certain balls can go through certain areas because of their size. If a coloured, transparent wall appears only the ball of that colour can pass. If two colours are set side by side it means either colour of the combination can pass. Press red buttons to activate certain things.
