Developer: Dejobaan Games Publisher: Dejobaan Games Platform: Windows Released internationally: January 25, 2008 This game has hidden bonus content.

The Wonderful End of the World is about a girl who controls a puppet to absorb as much of humanity as possible before the world ends, as one does.

Hidden Levels

While it's possible to be ranked on these, the score isn't saved anywhere and there's no leaderboard.

Portal

Hold P during the loading screen of Sugar Candy to access this Portal-themed level. Covers of "Still Alive" and "Want You Gone" serve as music, Companion Cubes are all over, and a line from GLaDOS plays if the puppet falls into the void. A delicious cake is waiting at the end.

Cubes

Hold U during the loading screen of Arcadia to access a level with lots of disco-colored cubes in it. The music is a seemingly original song about a hole in the ground.
