Hey! I made the music for this game.
That is mainly a fault of mine in my opinion, I was instructed to make 24 second tracks that could work for each "phase" some being rush hour.
I ended up accidently making them too far apart genre wise, so I am sorry about that haha.
It changing frequently is meant to represent each phase though, so that is intentional, although perhaps we should've made it perhaps not switch as fast.
