About the flickering, if several objects' side share the same x, y, or z coordinate(aka, they overlap), those objects will "fight" each other to be rendered on top, causing the flickering, my point being, that if you raise the y level of the streets by even 0.001, it would stop.
I'm very excited to join the jam! looking at the limited amount of people that joined, I would really like to show my support. I've recently gotten into development of 3d and 2d games. But I just turned 11. And I just want to clarify that it's fine if I join at this age and wouldn't cost you anything. Please inform me if yes!
