Solomon's Key
 Puzzle

1 million copies sold just in Japan. This game definitely is worth any penny you spent on it, the puzzles are a real challenge, while still is required a mint player execution. The music is good but after a while get too monotonous. There is only one bad thing in the game: Why the programmers did allow to pause the game in the level screen transition? and even worse What they didn't make an unpause sound? You can be pausing/unpausing forever without knowing if you paused or unpaused.
