Katamari Damacy Reroll is a remaster of the original Katamari game. In Katamari Damacy, you are The Dashing Prince, son of the King of All Cosmos. The King has gone and knocked all of the stars out of the sky after a heavy night on the tiles, sending The Prince out to go and tidy his mess up.
The basic premise of Katamari Damacy Reroll revolves around heading to Earth in order to roll up as many things as possible in order to recreate the missing stars. The size of the objects that can be rolled up depends on the current size of the trash ball. Players start small with paper clips and pencils, but entire buildings and continents can eventually be rolled up into a giant trashy ball.
