There's something I want to point out.
The art and gameplay are good. The only issue is the fps. I played your game many times and found out why it was lagging in the first place.
If you look at the image here, you will see that it loads so many instances, such as cars, dragoons and even buildings. Calculating everything, each character's movement on the sidewalks, some cars going and passing by and even building placement. If you look closely, you will see that it is also loading characters/cars way far away. There are some times when gameplay got smoother when it loaded, so a few instances, such as 2-3 cars/characters, and that's all.
It would be better if there were some settings which allow us to toggle instance generation or disable instances completely. For ex, the buildings, to make it smoother.
It is still my personal opinion, and I wanted to clarify. That's all.
