Answer 1

An interesting question, I also thought about it, I use Box2D physics and it turns out that in order for physics to work, I need to use images with a maximum of 16x16 pixels. I haven't uploaded real graphics yet, I'm only playing with Box2D objects.
I see 2 options so far
1. Use small vector graphics
2. Play around with the scale of the world

Answer 2

This question should be asked to the programmer who will work with your graphics.
