A really nice and tranquil, meditative experience. The music takes it - the dynamic changes especially were very atmospheric. I also enjoyed the setting of those old pirate radio stations.
One small thing: There was a bug where when you leave the broadcast seat in the back while keeping space pressed, it would continue to broadcast, but you could still drive and pump gas, sort of trivialised the challenge a little, but did not dampen my enjoyment, grooving out to driving down the endless road while broadcasting those pirate waves
Nice work :)
