It was okay. I wasn't sure what you were trying to do at first, as this music is was too complex for 8-bit or sure, and even for 16-bit. The instrumentation was not the same.
It was like half and half, and there wasn't very much variation in the baseline. Retro tunes tend to be sort of like jazz, they have chords and riffs that repeat in patterns throughout the song. You did that, just... not the same.
I really like the music, just not the presentation.
