its not bad
Melody: 1/2- the warping sounds are great for some notes, but it was too heavily used. I think you should use a gameboy synth for the lead and go nuts on the rest, for the sake of nostalgia.
Bass: 0/2- a louder/deeper bass would do wonders for this song. here, the bass is nearly playing on the same octave as the main in some parts. That is a big problem
Drums: 1/2- nothing special. if you have preset drum loops, use them like mad, it does wonders. it would really bring more energy into this song. i think with most programs you can add the bitcrusher effect onto presets too
Listenability: 2/2- its actually nice to listen to, the melody needed a little bit more reverb i think
Instruments: 1/2- its a remix, you dont have to copy the original. the instruments could be completely different if you wanted it to be.
OVERALL: Its half n half.
