Always nice to see someone put their own feelings through the ol' inspiration machine.
I realize this is less of a game than an interactive experience. It looks and sounds great, and the erasing function is good. I noticed if you start erasing too soon it triggers the timer for the next "page", which sometimes overlaps the voice lines.
From an artistic perspective I think that it could be an easy and fun way to add to the effect with different shaped brushes relevant to the memories. Like an eyeliner pen shape for the part where you mention makeup. Good job!
