Kirby follows where your mouse pointer is! Lead him away from the balls. Green is the slowest, Yellow is at a moderate speed and pink is the fastest of them all! Green is the only ball to appear at first, but at 20 seconds the yellow one is released, and the pink one at 40 seconds. (This gradual release was added in V2 to improve the difficulty scaling).
Shoutout to some random creators (I forgot who) for putting up posts where you can collect sprites and music.
