From you Review for Review reply, I understand that this is for an Android memory game app you're developing. First off, developing apps is awesome and I wish you huge success with it. Putting that much time into something like that deserves a lot of attention. (I haven't had much success but this isn't about me. :P)
Now that that's outta the way, let's talk about the song.
Wow. Sounds nice. I think that a *subtle* (emphasis on subtle) drum track could be used around 0:44 or something. I feel like that would get me more in the memory kind of feel. It's very simple, but that's what makes it so great! Like SCTE3 said it has that reflective feel that makes you want to just reflect on your past. There's not much to say about it but that's only because it's really nice and very simplistic which doesn't give me much to analyze. All in all, I love it. Keep up the good work!
Scouted :)
