Meet the Glutton
One hungry little monster
Big eyes, bigger appetite. The Glutton is a juicy, springy blob that squashes and stretches as it darts after its next meal — breathing, jiggling, leaning into every turn, and chomping with a satisfying punch.
It's the only vivid thing in the void — bright rim-light, bloom halo and a comet trail — so you always know where you are in the swarm.
