One thing I really like about the game is the music selection. Like, it's not fancy or anything. But, what's there is nice. I especially like the reminiscent music that accompanies the sketchbook scenes. It suits them so well, so I hope ttll doesn't change it to some thing else. I like that it's recurring, meaning you get to hear it on each and every one of those scenes.
I think in the future, the "past" will eventually come to an end in that sketchbook (not to suggest more memories of that time couldn't be invented if there's demand), but when the original, erased and scribbled-over sketches are all recovered, it will probably be time for those blank pages to be filled with /new content/. Meaning, pictures and perhaps scenes that happen with the mom, in the present time. That would be pretty great, if it turns out that way.
I guess, since the game is still in heavy development, more and more of those scribbled-out pictures could be found. So, we'll see. But I definitely would think it'd be hot if the untouched pages got filled in with what comes next, whatever that is. Oh, but I think that sketchbook should only hold the mom's images. Not images of the other girls he comes into contact with. Normal canvas is good for them. The sketchbook should remain special to only her and him...
