From Wikipedia: Lumines II[a] is a 2006 puzzle video game developed by Q Entertainment for the PlayStation Portable (PSP). It was released in November 2006 in Europe and North America by Buena Vista Games, and in February 2007 in Japan by Bandai Namco Games. The objective of the game is to move and rotate 2×2 blocks to form colored squares of the same color. Points are awarded to the player when the Time Line erases the colored squares. It serves as a direct sequel to Lumines: Puzzle Fusion, expanding on previous modes from its predecessor and adding new modes such as Mission mode, Skin Edit mode, and Sequencer. Lumines II utilizes songs from its predecessor and introduces music videos as background skins from Japanese music artists and mainstream American music artists such as New Order, Missy Elliot, and Beck.
