Wow! I really like this, quirky as fuck, kinda reminds me of some Mr Oizo tracks. I found there was just enough of the source in there for me to recognise, which is sweet IMO like a nice easter egg in the middle of an already good tune.
I like the synth Rukunetsu mentioned i thought it fits with the song rather well(shrugs).
The sound playing the main melody(vocalish) in the part after may sound better an octave lower perhaps? or atleast with a little more low end content to it. Having said that, as it is it adds to the quirkiness.
Anyway i'm in no way qualified to critique your music so feel free to disregard all ive said.Ill subscribe and wait for a finished version.
