Columns Crown is a very unique puzzle game that most people should enjoy. I have only played part of the US version, so I don't know any details about any other games that are in this series.First off, the graphics are very bright and colorful, despite being rather tiny. The little prologue/opening shown before the title screen is very cute and explains why the two characters are searching for the gems. It also provides very brief introductions for each of the three areas to find the gems in. I found it quite nice to have a puzzle game where there is actually an intriguing and fairly realistic storyline.
Also, the music is quite excellent, although I haven't heard that many songs. When a magical gem is used when battling an opponent, there is also a little sound effect (the name of the gem being used is announced..), and the unfortunate victime will recoil a few seconds later.
As a pleasant change from many video games, you have the option of controlling one of two characters. Before you enter one of the three main areas, you will be asked to select which character to use. The different characters will earn different gems in the same area, which means you need to balance your efforts equally between both of them. It's also nice to know that you aren't actually playing as the princess, but as her schoolfriends!
However, players will quickly learn that there is absolutely no way for the randomly-colored gems that appear in chains of three to be rotated sideways. While this adds another unique aspect to Columns Crown, it also results in the game being significantly more difficult than most puzzle games.
The survival mode also becomes very difficult very quickly, so this game may become too frustrating for young children. Players will have to spend much more time mastering Columns Crown than something like Puyo Pop. It's very easy to grasp the basic concept of the game, but it takes a veryyy long time to learn to play Columns Crown well (I'm still horrible..)
Still, for anyone who has the patience to try, try again, Columns' Crown is a vivid and addicting puzzle game.
