Nippon Ichi's Jigsaw World is bizarre in a few different ways. It's not a port, which makes it rare among NIS's DS games. It's not a strategy RPG, which makes it fairly unique among NIS's games in general. Oh, and also, it's an anime-style action game about completing jigsaw puzzles.
The latest screens of Jigsaw World, which comes out this month, show off the giant special attacks employed by each character, which affect both competitors and the puzzles themselves. For example, Mikan the cat/fruit crate (as far as we can tell!) can automatically fit a piece into the right place at the highest level of its explosive, orangey special attack.
