From what I can tell, the song used in this level is about a cat Cacola used to have who died.

Anyway, this is a really cool level. The design is pretty minimalistic, but the effects and the atmosphere make up for it. The gameplay, the song, the deco, the subtle camera movements, everything works together to create this feeling of returning home. The only issue at all I have with this level is that it's not immediately apparent that the part with the giant stars is freeroam; other than that, this is one of my new favorite levels.
