Feels like a theme that would play in a spooky game. This isn’t a race in the conventional way of race cars (though I think that is the point of this jam in this case), more like a race to escape something.
Reminds me to a lot of backrooms themed songs I’ve listened a lot.
I can’t say much about the time signatures usage since I’m not a professional musician, but I definitely can hear changes in the song and feels smooth.
Great job!
