The sender address of a packet is specified by the sender. So the game would be the same, you would just encode the pixel data in a different area of the same packets. Security folks call this "spoofing" but its just an aspect of how networking works.

You can prevent spoofing by using HTTP requests or similar, instead of ICMP echo. Similar to https://ipv4.games/ (but with a canvas and color selection)
