Thanks very much for the comments!
I definitely agree somewhat that we somewhat went for an overall quantity and story and maybe sacrificed some individual song quality, at least in terms of each piece not having much evolution in the musical ideas before they end.
We were trying to go for some fairly simple loops that could play in the background of some platformy levels, but I think next time we'll try to maybe do fewer tracks, but add a bit more musical complexity and evolution to each one.
