As I've promised, here I am!
HOLY, you weren't joking when you said you were also a toby fanboy! I can definitely feel the toby inspiration in each one of these tracks (especially "A Town of Your Dreams") and I love it! You definitely did a great job at making them feel similar yet different from the inspiration (something that I didn't really do that well lol).
Aside from the Toby Fox talk tho, the tracks themselves are also really well made! I can easily see each one of these being used for an RPG game. Although I'm an absolute sucker for boss battle themes, I think I have to give "My Imagination Rules !!" the title of my favorite track here. It's such an uplifting and adventurous track that definitely makes you feel like an amazing journey is ahead, amazingly done! That's not to say the other tracks are not as good tho, each one helps tell this story of yours really well and I applaud you on that.
Overall I really enjoyed this OST! I appreciate the Undertale influence and the instrument choice is also excellent. You did a great job telling the story you had in mind through these tracks and I congratulate you on that! Definitely up there for one of my favorite submissions. Thank you for letting my ears listen to such great tracks, you did an amazing job on these!
That's all I have to say really, have a wonderful day! :D
(P.S. I wouldn't attack Shadow in the final battle just to listen to "THIS IS MY WORLD" over and over again!)
