A more hopeful take on a post apocalyptic scenario which is always good to see, the guitar playing is really impressive for most of the soundtrack. A few tracks that stood out to me:
Boardwalk Halo is such a good song, I really like it. The bass near the middle of the song is absolutely phenomenal, it really reminds me of Hylics 2. Beautiful stuff.
Beach Games capture the mood of... Well, beach games, really nice. I actually got reminded of the last time I went to the beach to play ball with my pals lol
Twilight's Farewell remixes Boardwalk's melodies really well, it's a nice song, although I do prefer the latter's energy haha. Your insight on reversing the flute and violin was interesting to read.
With this being your first project in mind, I really enjoyed listening through it. Although I can't say I'm a big fan of the instrument you used for A World Left Behind, it feels a bit too loud. A minor gripe on an overall great soundtrack. I also enjoyed the story quiet a bit, this would be a rad game to play through. Well done!
