Just finished the game, and I really did like it. Well done.
Only a couple of criticisms/bugs...
*I think there were too many time cuts. The flashback scenes were used well and to good effect of revealing the plot little by little, but there were just too many of them in my opinion.
*A lot of the time when changing scenes (particularly when going to a character's speaking view, but not always) a little bit of text (not in a text box) would flash up on the screen, far too fast to see what it says, though.
*The ending was a bit... abrupt. It just sort of stopped.
*The English translation still needs work, I'm afraid. An example:-
I couldn't really tell what Dread and Peter were talking about between giving him the map and the pirates turning up.
The rest was functional enough, but not really fluent.
Other than that, good stuff. Great artwork and music especially.
