I think you took a very creative approach with the sound, though i feel like you didnt entirely stay closer to that more 8 bit style besides the lead and those backing pads (only mentioning this because you mentioned you were going more for that style). I vibe with the song overall but I think i dont entirely get the same interpretation as what you intended here, it feels like the main key in that feels more sad is the fact it is in a minor key, but the instrumentation choices outside of the guitar kind of make it seem a bit more positive in my eyes. Thats purely subjective but i just wanted to share my interpretation. Overall nice tho!
