First of all, I LOVE ALL THE ARTWORK!!! This is such a beautiful display of pure creativity, and your dedication has really impressed me. This game should be made! Find a programmer!
Songkeepers: First of all, with soundfonts being such a limited toolset to work with, you've made this sound really incredible. Applause for that! I'm curious about the moment where all the melodies are played in sequence. Perhaps there could be some space to play with counterpoint between the melodies, or have them blend into one another more? The main theme is just exemplary, and really accomplishes the adventurous feel you're going for.
Abel's Theme: Aww, this is so earnest and heartwarming. The B-section with the harp and pan flute is so sweet! I am rooting for this little fox boy so harddddd
Valor's Theme: So far, I appreciate the minimalism of these tracks. It fits the distinct soundfont style very nicely. It lets the music itself sing.
Sir Billsworth the IV's Theme: bassoon + silly, and if it ain't broke, don't fix it. This is just delightful. The pizzicato section is just so cutesy! You've used music to bring the characters to life, well done :)
That'll Cost Ya (Shop Theme): jazz was the answer. Head bobbing alert B-)
The Mad Ratters: This has to be my favorite!! Like yeah, these rats are up to no good. With every passing track I'm more sad I can't play this game...
Another big hidden gem for me. This one deserves fame and glory! It's certainly one of the most unique soundtracks so far, and the world you've come up with is very intriguing. Great work, and keep writing!
