Arthur’s Theme Song: Straight from the beginning, this sounds like an arcade game! The instrumentation sounds like a harpsichord which is an instrument that gives a lot of character to the music it is used in.
Jumping on Underground Clouds: The short loop is fun to listen to and would go well with the early 8-bit platformer type levels.
In the Hall of the Demons: The effect of this sounds like a voice! I am trying to imagine what it is saying… it kind of sounds like “I knew, I knew” over and over again. It’s a cool effect!
Trapped in Limbo: You used the perfect chord combination to musically describe limbo. Using a I to iii chord does not give any harmonic motion and makes us feel stuck without motion - perfectly conveyed in your writing!
Triumph!: This track gives such an optimistic feeling that would make me feel very accomplished at the end of this game!
Overall: This is a fun soundtrack for a short arcade-style game that I would definitely try playing! Good work and thank you for sharing!
