Not a masterpiece, but decent.
For Simulation RPG game, this game is not too bad.

Game is not too easy nor too difficult.

Character design is very nice, and story is interesting. Also there are sub-ending and episodes with four different heroine characters you can choose from.

However, the game is not perfect due to its short play time. (less than 10 hours to beat it once.)

But it will not be much problem because you will likely play this game more than twice. The choices you make in the game change many aspects of the game and make you experience new stuffs.

If you are thirsty for classic Simulation RPG strategic game, this game will be nice one to give a shot.
