The Wonderful End of the World. It's a clone of
Katamari Damacy, and an inferior one at that, but that isn't on PC. You can 100% it in about four hours, but it has
great music, and provides an ample amount of fun throughout its short lifespan.
It's also locked to 1024x768 resolution. It was released in 2008. Some mysteries are best left unanswered.
