First of all, the voice acting is perfect ! Too bad everything is not voiced, because it adds a lot to the mood of the game, I suppose you lacked of time to record ?
Everything goes really well together, the art, the sound, the story, the writing... That is really polished in every way !
And storytelling is so great, the story in itself is pretty simple, but you managed to give it a lot of character with the writing. I will play it again when I have time to see all the endings !
