The level of wavering that's going on in the melody seems to defy the essence of chiptune a bit! XD
Then again it does sound good, so never mind the superficial genre restrictions I've somehow confined in my mind there...
Feels almost like a pop song turned chiptune. It's catchy. Crisp chip elements with the beat; a melody that almost seems from another realm of hearing. It's kinda like autotune for chiptune... fascinating effect.
Good stuff.
