Thanks guys. :) Jiyoshi did this one.
As a fun little easter egg
;), there are actually a few musical nods to Cave Story throughout the track.
0:00 - End: The panning B note ringing on the upbeats throughout the song is a reference to egg corridor: Link
0:05: Reference to the main melody of Sand Zone: Link
0:17: Subtle reference to the main title theme: Link
And obviously the entire strucutre of the song is one big reference to On to Grasstown
