Very poignant.
This game is so simple aesthetically - dull in fact, when talking about gameplay, in truth. But I personally like that fact. Because that means the creator has thought so much about the content; the story and message of this piece of work.
Now while I would expect games of today to excel in both of these aspects, it has become more and more apparent to me that most games of today lack heavily in their stories and messages. This is a true shame, because to me, the games that do so well altogether are more moving than the most genius pieces of music or film. So because of this, it is so, so refreshing for me to see a clear thought out message in a game. I thank you for that alone.
...But there's a little more to this one.
The simplicity of the design makes the true intended message unclear to the player, and because of this vagueness it leaves the player to surmise its meaning themselves. But of course, that is the true intention of the creator.
My idea? I liken this game to Final Fantasy X, albeit an extremely shortened version (obviously, haha). My reason is because I believe the story is pretty much the same. Our hero in Grey Story (Tidus) is trapped in a desolate world with a girl he is fascinated with (Yuna), of whom is too preoccupied with whatever else to take real notice of him. But as he realises he can make a difference to the world, he fades as he fixes it. His action of fixing the world around her attracts the attention of the female and makes her much happier, but before the two can enjoy the world after it has been rid of the dullness, it is too late - he is gone. So the girl is left to live in the fixed world by herself.
That's just me. Anyway, back to my review. In short, I thought it was fantastic. The score suited the game well and there were no problems with whatever gameplay there was. The artwork was simple yet clever with the colour co-ordination. You deserve a pat on the back, my friend, well done.
