Here's one of the amazon reviews in English:
My impressions after clearing 5 scenarios the other day.
I usually don't play games, but this is the first one I've bought in 2 years.
I bought it after being attracted to the low price and the artwork.
As everyone says, the shortcomings are very glaring.
It's difficult to check the status disorders of individual characters, and being unable to skip dialogue from stages you've already played once is annoying.
Most of the game is pure battle and it gets tiresome. the number of items you can purchase is limited. Calculating the results from overkill techniques is a crapshoot, and you'll never know how much damage will be done until you do it.
Even when I try especially hard to plan an overkill, I'll find myself missing by 10 or 5 points and ending in failure. This has happened so many times that I want to scream.
It's a game that's very unkind to players.
But I played the game thinking of this unkindness as the game's special idiosyncrasy.
Many mention that there's no Free Battle in the game, however I think the game would be finished too quickly if there were one.
Perhaps the game gets interesting the second time around...
The first time is frustrating and tiresome(because of your party being too weak, etc.).
At first I was trying hard to beat it, but I gave up on my first time through.
The art and music are high points, but the game mechanics are broken.
Having my overkill techniques fail me was the most frustrating part.
I can't count how many times I repeated the same stages(if only I could save mid-stage even one time!)
Also, the time limits that let bosses get away after you've been whittling away at them will bring you to tears.
There were a lot of frustrating aspects to the game, but the story had some surprising parts, and it was pretty enjoyable.
So I'd give it 3 stars for being interesting. However, as a complete product I'd give it two stars.
....On the plus side, even if you're strapped for time you can be done with it quickly.
