Real heart touching story. And I would say: very well paced and the ending really made me go O.O
But, Mr/Mrs. Developer, if you're reading this I have two feedback for this game:
1. For dialog, avoid making them call each other's names in every single sentence, it'll make it sound more natural (esp in english).
2. Some sound effects are wayyy too loud imo better mixing would do a lot.
But other than that, the game is great! Really making the most out of the limitations that you had, I was really really scared even though there was nothing, great atmosphere. Hope to see Family Secrets 2!
