Worlds
From the dream world nexus, there are three accesible doors, to Time World, Sugar World, and Forest World, and one you can enter at the end of the game, which leads to Allan's house. Sugar World
A pink sea studded with what appear to be candy-canes in bent shapes (or straws) and lemon slices. If you sit at the bench in the small bus stop in this world, you will be transported to the Windmill Panorama and then the Bus Area. There is a paper airplane floating around that transports you to a world full of scraps of large paper airplanes and pillars with paper airplanes stuck all over them.
Interacting with the fat, bleeding candy cane transforms the world into a slightly creepier version where the sea is dry and there appears to be red and blue pills littered everywhere. Some are broken, leaking green liquid. There is a set of brightly coloured syringes, crossed like swords.

Forest World
An area with snowy white paths and pink and blue pine trees. The only NPC here is a yellow comet from which you receive the Comet effect. There are two doorways here to get to other worlds -- a blue sketch pad with a hole in it, and a large blue house.

Ending
Once all nine effects have been found, the player is given access to the previously locked white door at the end of the hall. Opening it leads A to an empty white area studded with trees, flowers, and some of the scenery from the Sugar World. Heading north for a while causes the screen to fade to white and enter a new scene.
A boy with brown hair is sitting in a bed next to a TV. A woman, presumably the boy's mother, enters the room and looks at him. The scene changes again.
You are now playing the boy. If you access the menu, you will see that despite the fact your character image is the same (the letter A), your name is now Allan. The woman from before is at a kitchen table, either dead, wounded, or asleep next to a pile of what appear to be fruit shavings or pills with a paring knife (perhaps the same kind from the Fruit Knife effect). The kitchen she is in is barred off, so the player is left either to explore the limited TV room or enter Allan's bedroom. Once entered, you cannot exit. The only interactable items in the room are a picture of a flower and an empty notepad next to some markers. Interacting with the notepad leads to the next scene.
The mother wakes from the table, but the house is now unsettling colors and infested with white worm-like creatures everywhere. Contrary to when you played Allan, the menu cannot be accessed at this time. The only option is to enter Allan's room, which has also become distorted. You'll find the boy where you left him off -- except he is now a Medusa-like monster with a brown tangled head covered in red eyes. The mother carries the paring knife from earlier, and interacting with the monster from the front will make her kill it. You hear Allan-monster's scream and the screen fades.
