4-2 BUSTLING BLOCKLAND

In my design doc, this stage had sections where you'd ride a train, kinda like the interlude in 2-1 where you hop on an airship for a bit. There weren't any mechanics associated with it, just a change of pace and an excuse for some fast-moving parallax.
Most of the music in SomnaBuster is inspired by other game tracks but this one specifically might as well just explicitly be stolen, I admit that wholesale. I actually had a panic attack and had to change this song's chords and lead because it went beyond just imitating the chord progression and outright copying it.
