    Wow! An original and mature puzzle game for Sony's shiny new trinket! I think that puzzle games of this type fit handheld gaming really well. The levels in this game are well judged, always taxing but beatable. Many of them make you think 'No Way!' until you crack them after a few practice runs. It makes a nice break from the reaction puzzles of Lumines. A couple of Wow! An original and mature puzzle game for Sony's shiny new trinket! I think that puzzle games of this type fit handheld gaming really well. The levels in this game are well judged, always taxing but beatable. Many of them make you think 'No Way!' until you crack them after a few practice runs. It makes a nice break from the reaction puzzles of Lumines. A couple of blemishes on this game are a lack of auto save (why? surely that takes about 15 miuntes to code and is a feature in every title since whenever!) and long load times meaning that it isn't as pick up and play as it could be. You may find yourself relying on the suspend feature a lot. Also, to get the unlocks is simply impossible. To get all the high scores needs reference to an online guide or a sociopathic addiction to this kind of game. They're uber-hard. If you enjoy original puzzle games you won't be dissapointed with this. Maybe a sequel will iron out the rough spots and give us another great game?! More games of this quality and originality on PSP please! Expand

  1. It doesn’t really have the endless appeal of something like "Lumines," "Puyo Pop" or "Tetris," but the problem solving, logical puzzles and interesting physics make it nonetheless enjoyable.
  2. The unique gameplay and puzzles, as well as the balanced increase in difficulty, makes for an addicting and rewarding experience. There may not be too much replay value in this one, but it’s definitely entertaining enough to give it a shot.
  3. When Mercury is at its best, it's an elegantly simple and addictive action-puzzler. When it's at its worst, it's like a tedious pop quiz from an unpredictable, bad-tempered teacher.
