Bongos!
Haha, pretty neat song! I liked it. The bongos that come in at 1:31 really saves the song for me. It's cute. Not in a condescending way... in a cute way.
Without reading how the song is represented by you, I'd say it reminds me of leaving childhood. The happiest times of your life slowly drifting away. You learn that life isn't as simple as you thought it was.
I found it quite moving/touching. Good job. to be touched by an 8-bit sounding song really means alot. Nice writing. Do me a favor and return the favor with my music sometime! I'd appreciate it! Thanks!
