Move camera with the aswd keys. Game might take a while to initialize all ants.
Made in two hours from scratch. Adding new pixels under the ant was really hard to figure out. The red dot is where the ant is. Every tick the pixel under the ant is flipped, then the ant moves forward. If the pixel under it is ON (white) the ant turns right. If its OFF(black) It turns left. It is purely computational and uses ZERO touching detectors. Usually reaches a loop at about tick 10,000
