    A really enjoyable small game. You have to know that this is really a small game but it's well executed. The puzzles are fun and the controls tight. It's fun to compete with the online leaderboards. The musics are great and the levels are variable, I truly recommend this for anyone who want's a game to play in between bigger games.

  1. Both Mercury-games were released during the early years of the PSP. The games still play as they did before and look pretty neat in their HD-iterations. [Nov 2011, p.97]
  2. Like the periodic table? You're in luck, because Mercury HG is flipping obsessed with it. [Christmas 2011, p.109]
  3. The colorful, grid-based maps shift and turn in surreal ways, lending a truly distinctive feel to the game. [Holiday 2011, p.84]
