It's really cool how you came up with such a thorough idea for a game, then portrayed various scenes in it with your music. The changes in instrumentation, rhythms, and tempo really helped with vividly telling your story. Great job!
Yes, I have come to discover that I compose music best when I have a prompt of sorts. I can't really just sit down and start writing music without having some idea in my head. That's why these game jams have been so fun and productive for me.
