I congratulate you. You made an beautiful game. It made me cry, but mostly think. It has a very realistic story, and I feel kind of concerned about it, because my friend's mother had this problem has well.(don't worry, she allowed me to tell about it) This game is uncommon, but it makes a great difference with what I'm used to.
Oh, and I offer you my condolences for your grand-father. I know it's hard to lose someone you love, and I hope he died peacefully.
