The port isn't very good, but man, I loved this game back when it was first released on the PSP. The clean graphics, good music and addictive gameplay; it all made sense. The goal is to create cubes (by using cubes). The cubes that fall down have two colors so you have to match them and try to make as many cubes as possible before the 'beat line' moves over them. It's really a line that moves from the left to the right (apparently on the beat of the music, but I'm usually too focused to notice) and clears the cubes. Of course things speed up after a while until you are overwhelmed. It has a lot of similarities to Tetris actually (it's hard to create a game like this these days that doesn't use Tetris elements so I can live with it. Besides; Tetris rules !). Anyway, the game itself is definitely worth it, the port itself, however... not really. If you can get it cheap, do yourself a favor and get it immediately though.
