Hey guys it's my first LDJAM any advise?

Feeling super excited. My first game jam ever. I will try to finish the game. Started prep. Brushing up coding skills and just animated walk cycle for a pixel Mario:-$

I will be using the following software-:

Unity Gimp for 2D assets Blender for 3D assets Visual studio Bosca ceoil magicavoxel(never tried it though so, may be)

Wish you all a great jam!!!!

I am making a 2D endless runner game. I want the background to change and move constantly. And different type of objects to come as obstacles. I am confused as to how to go about it. How can i spawned different backgrounds so that it looks constant.
