You did a really good job replicating the ui and sound! I especially liked the animation when it would switch from day to night shift. I think my greatest critique would be with the art style - for some sprites such as the trees and the sprite where you hit a biker, you used these sort of paintbrush like textures. Alternatively, there were sprites like the bullet or ui which had thick, solid outlines and no texture, and they stick out quite alot as a result. Additionally, the colors feel a bit too saturated in comparison to the original game, the sky especially. Overall though, it's a really well done clone!
