Korogashi Puzzle Katamari Damacy

_Korogashi Puzzle Katamari Damacy_ is a puzzle game based on the _Katamari_
franchise, with mechanics reminiscent of Pac-Attack. It revolves around
stacking items and it looks like a regular falling-block puzzle game, but the
pieces do not appear automatically from the top of the screen. The game is
played by holding the DSi sideways, with a double portrait view, and it is
played entirely on the right side. On a roster with a size of six boxes
horizontally, blocks and items such as fruit need to be dropped. They appear
on the right side in a preview area where they are pushed up by the cousins
with a steady pace. The player selects and drags them to the roster using the
stylus and then they drop down from the chosen horizontal position
automatically, stacking on top of the ones below.

Every dragged item has a certain form, like an L-shape or a square of four
elements. Every now and then the Prince appears. When he is dropped he follows
the route that has been created with blocks to eat up the fruit and other
items, creating more space so everything stacks again. This is the same
mechanic as in _Pac-Attack_. The remaining blocks that then form a full
horizontal line disappear, Tetris-style. The player needs to arrange the items
in such a way that a long, interrupted passage surrounded by blocks is created
for the maximum score and keeping the roster empty.

Most levels have a time limit and a goal to get a certain amount of items.
These items are rolled up by the Prince using a rolling ball or Katamari,
which then grows in size, show on the left screen.
