I just finished this, the game is basically on rails from start to finish. the translation is at best a lightly edited machine translation. The story was really dull, so it doesn't really take away much anyway. near the end there are two game overs caused by blue chests. One actually caused it to error and crash, so be careful of that in case it wasn't just on my end. I would suggest not bothering with this unless you really like the art. At least there didn't seem to be any scenes you needed to lose battles to see.
On a side note, I somehow missed a scene I assume is called H2. If anybody knows where in the story I'd appreciate it. The only are that comes to mind is I might have missed something on the ship. hmm...
