Songkeepers: Some upbeat percussion to start. Nice and sweet melodies, as well as a cool ending.
Abel's Theme: Loved the use of pan flute. Really gives the vibe of an early game character theme.
Valor's Theme: Getting a bit darker. Love the harp arps. My favorite track here!
Sir Billsworth the IV: Starts off feeling silly (matching the character) but with a deeper side showing when the strings come in. Nice work.
That'll Cost Ya: Apt name, love these chord choices. Strong shop theme vibes.
The Mad Ratters: This gives me a cartoon villain vibe which matches the story you've written. Very well composed.
Nice work!
