Fantastic job! The pixel art came out superb!
Just one thing: It’s not a critique, just an opinion, but IMHO, the background could be a little bit darker and mainly a little bit colder in terms of color (yeah, it’s a meat world haha, but that would help create contrast to improve visibility when in motion. It’s a common technique to separate the background without really changing the color too much — for example, making a gradient/dithering (10% to 20% of the total vertical area) from a warm tone (reddish) to a slightly cooler one, maybe near magenta).
But overall, the visuals are stunning and nostalgic, really, a GREAT good job in pixel art o/
