Arrow keys to move the camera view around. Run into a ball to kick it off into void. It will explode into some mini balls, and a new ball will spawn. I was playing with moving a camera view and objects in a 3D space, and learning how to sort objects by depth so the "closest" object appears in front of farther objects.
I got the idea and the ball sprite from a sprite depth sorting project, https://scratch.mit.edu/projects/307388424, by griffpatch_tutor. https://scratch.mit.edu/users/JimboJones47
