Pixel Poops: Number Two

You've just learned that those ambitious, motivated joggers are out and about all over...from the park, to the middle of town, all the way to the graveyard! You've decided that it's your responsibility to stop them once again, armed with just your lightning-fast metabolism, and a fully-loaded gift card from the taco place! And this time, you can bring a friend along for two-player simultaneous play! That's right, the size of the poop-parazzi has doubled! Once again, small poops will only slow the joggers down. But keep pooping, and your poops will grow to massive size! Giant poops stop the joggers for good and score you points! When your chamber is empty, fill up at the taco place! And don't let too many joggers get away, or it's Game Over!
