Excellent! I thought it was going to be simple chiptune. No, it's much more than that. I don't know if you know Anamanaguchi, but for me it's very close. I love the sound you send us at 0'23". That's when you realize you're dealing with a great composition.
On the other hand, I wasn't convinced by the slow return of the growling bass from 1'13". That's just my personal taste.
Otherwise, the melody is sublime and the choice of chords is top-notch. Your music transported me.
