Nintendo has today announced that Polarium will see a sequel this year, with Polarium 2 due for release for the Nintendo DS later this year.
Polarium was a launch title for the Nintendo DS when it launched in February, and is a simple pick up and play puzzle title. The gameplay of the sequel will be similar to it's predecessor, but include more puzzles, a Time Attack mode and a more complete Edit mode. Instead of just appearing in black and white, the game will be in full colour.
Polarium 2 is pencilled in for release in Japan on October 13th, as is the Gameboy Advance version, which appears to be the same in content. As soon as images become available, we'll have them.
