Unlock World 1 and the Epilogue
To be able to reach the door in the attic that allows you to enter World 1 you must first repair the ladder in the house (level select area). This is done by finding ALL 72 puzzle pieces and assembling each world's jigsaw puzzle. When you have beaten World 1 you will be taken directly to the Epilogue which you can return after beating it any time you want by walking into an offscreen alcove which is reached by going left at the 'Title' screen.
