"This is quite abstract and surreal," was the first thought that came to my mind after I hit play. Makes me wonder what is on this 'other side' of the world you've created.
The author comments would have been ideal to explain your reasoning behind this song in more detail, but you may have simply wanted to keep us guessing or come up with our own reasons why, which is ok because I would do the same thing.
Since the song is short, I've been listening to it on loop to try and get a better understanding of what's going on. The brushing sound that is prevalent throughout the track almost sounds like ocean waves, or wind rustling through palm leaves. I think to the layman, this is just a short piece, but to me I believe you've put quite a bit of thought into your work and I am thankful that Newgrounds still has musicians like yourself contributing their talents.
Excellent work as always.
