Creative idea, but somehow empty...
This does get a little annoying, and I don't see why, from all things, you use FL's opening blip, but yeah, it's creative, and it's what gave you the majority of your points.
Melodies were OK; they got a little monotonous at the beginning, but the closer the song got to the end, the better the melodies became. Your use of the blip was quite creative, but at 0:05, the blip you used in the background got a little annoying, so maybe instead of doing it once every beat, do it once every four beats at the beginning.
Transitions throughout the song were nothing too special, and I quickly lost the rythm of the song. I think you should make simpler melodies, since by using two melodies at the same time being played by one sound makes the song sound cluttered and complicated.
Intro, as Haggard said, was nothing too special. What I think would be better is if you made an awesomely catchy melody play first, and then it gets a little more complicated. The ending was a little wierd, but it would've been OK if you added more silence to the end.
You could try adding some drums over here, just to add a little more rythm, or maybe you can use the default drums of FL Studio to make the song sound more FL-ish :P.
Creative idea, but it wasn't performed to it's best. Using one sound only to make a song isn't the easiest to work with; maybe you can try other sound packs (you already tried Windows...). Still, you have a creative idea going on, just work on it a little more.
