You definitely captured a style that first came to mind as soon as I saw the picture provided for the jam theme. Really nice touches and appropriately subdued in a lot parts. Reminds me of a game like Kingdom where the game kind of seamlessly moves between phases and the music with it. Nice work!
Only other feedback I have, more out of personal taste, is that I would love to hear one more uptempo track to really provide a contrast to the others. Either way good stuff!
