You are the rainbow worm You hit the right arrow to move right and the left arrow to move left. The goal is to avoid the weird reddish square at the top that clones itself and moves down. This game is basically trying to get as many points as you can in a minute without hitting the red square, which resets your points to zero.
All Credits to GoldiePoke for the Original game, but the game would glitch, so I fixed it. Hope you enjoy! (If it doesn't start right away, press the green flag again.)
