overall I've played till the end of the game, and just got to like 3/4 endings, it's a decent-good game. I enjoyed it. There are number of things that reset back some places, and I'm unsure if it's a bug or intentional.
the only sad thing, the ending video/movie crashes/freezes the game at random point of the video, making the credits unplayable. I think this is mostly game engine/RPG Maker problem at this point, as I had seen this issue already on another game before.
(Also any or anyone has hint for the secret one? at least what conditions.)
Again, regardless of the problems, it's still again, as I mentioned a decent to good game. And I enjoyed it till the end. It's fun!
