A solid 2D fighting game.

Pro:
There is single player (further divided into Story Mode, Arcade Mode, CPU Quick Match, Marie 300% hidden in extra) and Versus (Tournament Mode, Local Only, Quick Match, and Lobby Play). I mainly played Story Mode (Marie sometimes can be truly godlike hard to beat) and Arcade Mode. Each character has a unique background story which is a plus.

The in-depth tutorial can help players to learn the game quite a lot. Fighting mechanics are very well explained in the tutorial (warning, the full tutorial is long. If you are using the keyboard to play the tutorial, you might not pass a certain level due to the control). There is also a training room in the game to help you practice each character, learn their strength and weakness, and master their abilities (It will take quite long to remember all the combo, you can also find the command list for all playable characters under Help and Option).

The art style and animation of the characters and the background are great and unique (mainly the characters, cute and cartoonish). Of the 8 base game characters, Ms. Fortune is definitely my favorite (Love her victory pose).

The soundtracks (scores) are cozy and suitable for story cutscene, fighting, or even just in the menu.

Cons:
One small thing I do not like about this game is the very weak keyboard control (So if you want to master this game, a controller is highly recommended). Some of the combos are extremely hard to pull even in a tutorial let along in a match.

Another is the over-sexualization of some characters which are not really needed (but if you are into the stuff, ignore this sentence)

Overall:
It is a great fighting game. Also, make sure to check out the Art Gallery in the Extras. A lot of them are beautifully drawn.
