Armageddon is drawing near and the world as we know it is going to end. It is up to the player to collect as many items as possible before it all vanishes.

The Wonderful End of the World is best described as an adaptation of the Katamari concept. Players explore 3D worlds to collect and absorbs items, which then orbit the main character and make it grow, allowing larger items to be grabbed. This game contains worlds with a typical Katamari look as well as high-tech sci-fi environments. There are twelve worlds in total and all with an entirely different theme.

The game can be controlled through the keyboard or the mouse and there are three game modes per world (not all available right away): timed, timeless and exploration. The game keeps track of the best times and scores, contains a tutorial and achievements are collected in a separate trophy box.
