Congrats on first game jam.
Scope can be a difficult thing, desire, ambition and expectation can be shattered by reality.
It's part of the fun of the jams.
Music has been one of the things I've really been trying to improve, I'm not musically trained, so basically had to start from zero on it, but I'm now able to produce music that I don't think is bad, maybe rough around the edges or in need of improvement, but not bad at least.
